Product Overview2N2222A is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. The maximum amount of current that could flow through the Collector pin is 800mA, hence we cannot connect loads that consume more than 800mA using this transistor. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA. When this transistor is fully biased then it can allow a maximum of 800mA to flow across the collector and emitter. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (V­CE) or Base-Emitter (VBE) could be 200 and 900 mV respectively. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around 660 mV. This blog will introduce 2N2222A systematically from its features, pinout to its specifications, applications, also including 2N2222A datasheet and so much more. Video: 2N2222 NPN Transistor as a switch - Arduino example with LED Flash CatalogProduct Overview2N2222A Features2N2222A Pinout2N2222A Equivalents2N2222A CAD ModelsHow to use 2N2222A Transistor2N2222A Advantages2N2222A Disadvantages2N2222A Applications2N2222A Specification2N2222A Manufacturer2N2222A DatasheetUsing Warnings2N2222A FAQ 2N2222A FeaturesBi-Polar high current NPN TransistorDC Current Gain (hFE) is 100Continuous Collector current (IC) is 800mAEmitter Base Voltage (VBE) is 6VCollector Emitter Voltage (VCE) is 30VBase Current(IB) is 5mA maximumAvailable in To-92 Package 2N2222A PinoutThe pin configuration of the 2N2222A transistor is shown below.

The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. This transistor will make it forward biased and thus closes the connection between collector and emitter. However one important thing to notice is the Base resistor a.k.a current limiting resistor. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. The value for this resistor can be calculated using the formula: RB = VBE / IB. To make things simple I have shown a simplified circuit to make a transistor as switch. In actual circuit modifications might be required. I have used a base voltage of 5V and a value of 1K as current limiting resistor. Simplified Circuit Note that the motor here draws about 500mA from the 12V power source, since the 2N2222 has collector current rating upto 800mA this circuit is possible had it been a BC547 the transistor should have been burnt. 2N2222A AdvantagesThe main advantages of using the 2N2222 transistor include the following.This is the most commonly used type of transistorIn electronic circuits, most of the switching applications can be done by using this transistorIt is capable of handling fairly high magnitude currents as compared to other similar transistors.This transistor switches the load current with 800 mA through it, which is high as compared to others.So this capability will make the device ideal in the applications of linear amplifiers.Small sizeLess weightVoltage gain is highLow source voltageLow costLonger life 2N2222A DisadvantagesThe main disadvantages of using the 2N2222A transistor include the following.SensitiveDepends on TemperatureInput impedance is lowFaults cannot be found easily due to small sizeIt is extremely hard to replace with new ones by unsolderingIt does not function efficiently like a relay or electrical, mechanical switches. 2N2222A ApplicationsThe applications of the 2N2222A transistor include the following.As compared to the normal NPN BC547 transistor, the 2N2222 is extremely similar, but 2N2222 allows 800mA of collector current & also 652mW of power dissipation which can be utilized for driving larger loads as compared toBC547.So, the 2N2222 transistor is the best choice for switching high current loadsThis kind of transistor is mainly used for amplifying currentThis transistor can be used as a switch for automatically switch ON/OFF any appliances.It is used for PWM due to its quick responseBecause of its fast response time, it can be used for pulse width modulation.It is typically used in automation & embedded projects.Audio PreamplifiersSensor CircuitsAudio Amplifier StagesUsed to switch several loads simultaneouslyRF CircuitsDarlington PairsThese transistors are used in Motor drive circuits like VFD or variable frequency drives.Used in Rectifier Circuits & DC InvertersIt is used as an amplifier to amplify voltage, current & power.Darlington pair transistors are used for attaining the maximum current from the emitter terminal to the collector. 2N2222A SpecificationProduct AttributeAttribute ValueManufacturer:MicrochipProduct Category:Bipolar Transistors - BJTRoHS:NMounting Style:Through HoleTransistor Polarity:NPNConfiguration:SingleCollector- Emitter Voltage VCEO Max:50 VCollector- Base Voltage VCBO:75 VEmitter- Base Voltage VEBO:6 VCollector-Emitter Saturation Voltage:300 mVPd - Power Dissipation:500 mWMinimum Operating Temperature:- 65 CMaximum Operating Temperature:+ 200 CPackaging:BulkDC Current Gain hFE Max:325 at 1 mA, 10 VDCTechnology:SiBrand:Microchip TechnologyContinuous Collector Current:800 mADC Collector/Base Gain hfe Min:75 at 1 mA, 10 VDCProduct Type:BJTs - Bipolar TransistorsSubcategory:TransistorsUnit Weight:0.082453 oz 2N2222A ManufacturerMicrochip Technology Incorporated is a leading provider of smart, connected and secure embedded control solutions.

BC547 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. The maximum amount of current that could flow through the Collector pin is 100mA, hence we cannot connect loads that consume more than 100mA using this transistor. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA.When this transistor is fully biased then it can allow a maximum of 100mA to flow across the collector and emitter. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (V¬CE) or Base-Emitter (VBE) could be 200 and 900 mV respectively. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around 660 mV.BC547 ApplicationsA lot of applications associated with BC547, a few of the main applications are given below.Sensor CircuitsAudio Preamp circuitsAudio Amplifier StagesSwitching Loads under 100mATransistor Darlington PairsRadio Frequency CircuitsBC547 Transistor FeaturesPackage-Type: TO-92Bi-Polar NPN TransistorDC Current Gain (HFC) is 800 maximumMax Collector current (IC) is 100mAEmitter Base Voltage (VEBO) is 6VMax Collector-Base Voltage (VCB): 50VBase Current (IB) is 5mA maximumBC547 Environmental and Export ClassificationsAttributeDescriptionRoHS StatusROHS3 CompliantMoisture Sensitivity Level (MSL)1 (Unlimited)BC547 Working PrincipleWhen the input voltage is applied at its terminal, some amount of current starts to flow from base to the emitter and controls the current at collector. The voltage between the base and the emitter (VBE), is negative at the emitter and positive at the base terminal for its NPN construction. The polarity of voltages applied for each junction is shown in the figure below.BC547 Package InformationSOT23(TO-236AB)SOT323(SC-70)SOT416(SC-75)SOT883(SC-101)Where and How to Use BC547The BC547 is a widely used transistor and it can be used in any general purpose application, it can also be used as a substitute and replacement to many transistors, therefore it can be used in variety of electronic circuits for example switch small load on very low input voltage and current and also in amplification of small audio and other signals. The max transition frequency of the transistor is 300MHz so it will also perform well in RF circuits under 300MHz frequency.How to Safely Long Run BC547 in a CircuitFor long run in a circuit it is important to not increase load more than 100mA on it, and do not exceed the voltage across this transistor to 45V DC. Always use a suitable base resistor to provide required current for saturation. Do not use or store it in temperature above +150 centigrade and below -65 centigrade. Always confirm the collector emitter and base pins before placing in circuit. If accidently placed wrong in a circuit than check its performance again because placing wrong pins sometimes burns the internal circuitry of the transistor or make it weak.How to Protect BC547 TransistorFor the long life of bc547 do not increase load more than 100mA on it, and do not exceed the voltage across this transistor to 45V DC. Always use a relevant base resistor to provide the required current for saturation because more current on base can damage the transistor. The temperature does not above +150 centigrade and below -65 centigrade. Always confirm the collector-emitter and base pins before placing them in the circuit. If accidentally placed wrong in a circuit then check its performance again because wrong input can decrease its efficiency.BC547 PNP ComplementaryThe complement of BC547 is PNP BC557, BC558.BC547 Replacement and EquivalentYou can replace bc547 with bc548, Bc549, 2N2222, 2N3904, 2N4401, BC337. The Pin configuration of some transistors is different from BC547 so check pin configuration before replacing in a circuit.BC547 SMD EquivalentThe SMD of the BC547 is available as the BC847, BC847W, BC850, and BC850W.BC547 as SwitchWhen a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. As discussed a transistor will act as an Open switch during Forward Bias and as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin. As mentioned the biasing current should maximum of 5mA. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. The value of this resistor (RB) can be calculated using below formulae.RB = VBE / IBWhere, the value of VBE should be 5V for BC547 and the Base current (IB depends on the Collector current (IC). The value of IB should not exceed mA.BC547 as AmplifierA Transistors acts as an Amplifier when operating in Active Region.

This mosfet can drive loads upto 23A and can support peak current upto 110A. It also has a threshold voltage of 4V, which means it can easily driven by low voltages like 5V. Hence it is mostly used with Arduino and other microcontrollers for logic switching. Speed control of motors and Light dimmers are also possible with this Mosfet since it has good switching characteristics.So if you are looking for a Mosfet to switch applications that consume high current with some logic level devices then this Mosfet will be a perfect choice for you.How to use IRF540NUnlike transistors MOSFET’s are voltage controlled devices. Meaning, they can be turned on or turned off by supplying the required Gate threshold voltage (VGS). IRF540N is an N-channel MOSFET, so the Drain and Source pins will be left open when there is no voltage applied to the gate pin. When a gate voltage is applied these pins gets closed.The below circuit shows how this mosfet behaves when the Gate voltage is applied (5V) and not applied (0V). Since this an N-Channel MOSFET the load that has to be switched (in this case a motor) should always be connected above the drain pin.How to use IRF540N?When you turn on a MOSFET by supplying the required voltage to the gate pin, it will remain on unless you supply 0V to the gate. To avoid this problem we should always use a pull-down resistor (R1), here I have used a value of 10k. In applications like controlling the speed of motor or dimming a light we would use a PWM signal for fast switching, during this scenario the MOSFET’s gate capacitance will create a reverse current due to parasitic effect. To tackle this we should use a current limiting capacitor, I have a used a value of 470 here.How to Connect IRF540NIt’s quite simple, and must be done as explained in the following points:The source should be preferably connected to the ground or the negative line of the supply.The drain should be connected to the positive terminal of the supply via the load which needs to be operated by the device.Finally, the gate which is the trigger lead of the device should be connected to the trigger point of the circuit, this trigger input should be preferably a +5V supply from a CMOS logic source.If the trigger input is not a logic source make sure the gate is permanently connected to ground via a high value resistor.When the device is being used for switching inductive loads like a transformer or a motor, a flyback diode should be normally connected across the load, with the cathode of the diode connected to the positive side of the load.However, the IRF540N has a built in avalanche protective diode, therefore typically an external diode may not be required; it may be incorporated in case you wish to provide extra safety to the device.Corrections to the above explanations is welcome.Component DatasheetIRF540N DatasheetFAQWhat is IRF540N?The IRF540N is an advanced HEXFET N-channel power MOSFET, from International Rectifier. The device is extremely versatile with its current, voltage switching capabilities, and thus becomes ideal for numerous electronic applications.Why Do We Require IRF540N?The IRF540N is an N-Channel MOSFET. This MOSFET can drive loads upto 23A and can support peak current upto 110A. It also has a threshold voltage of 4V, which means it can easily driven by low voltages like 5V. Hence it is mostly used with Arduino and other microcontrollers for logic switching.Can I Use MOSFET IRF540N as an Arduino Switch?Arduino using MOSFET IRF540N as a switch for a motor No that makes no odds at all. The first problem is that you have not set pin 12 to be an output in the setup function. So that pin is an imput and you are just turning on and off the internal pull up resistor.How Does IRF540N Work?This section of the tutorial will elaborate about the basic working principle on which IRF540 works. IRF540 works on a simple principle. It has three kinds of terminals e.g. Drain, Gate and Source. When we apply any of the pulse at its Gate terminal, its Gate and Drain gets short i.e. they make a common connection with each other.How Do You Use P Channel MOSFET?To turn on a P-Channel Enhancement-type MOSFET, apply a positive voltage VS to the source of the MOSFET and apply a negative voltage to the gate terminal of the MOSFET (the gate must be sufficiently more negative than the threshold voltage across the drain-source region (VG DS).

The device contains two parts one is an IR LED and the other part is the phototransistor. The working of the device is simple when power is applied to the IR LED which activates the LED, the IR light is detected by the phototransistor and as a result the transistor become saturated or switched ON. There are two base of the internal phototransistor from which it can be controlled one is the photo detection or IR light detection and other is connected with the pin6 of the device, therefore it can be controlled by two procedures at the same time.The max collector-emitter voltage of the phototransistor is 30V and max collector-emitter current is 150mA. However the collector-emitter saturation voltage is from 0.14 to 0.3. Normally the saturation voltage of transistor is 0.6 or 0.7 volts but 0.3 volts is an ideal saturation voltage for applications where low voltage saturation is required.As regarding the IR LED characteristics the max forward current is 60 milliampere and max power dissipation is 120 milliwatt. Pin3 is labeled with “NC” which means the pin3 have not connection with the internal circuitry.4N35 EquivalentsPart Number DescriptionManufacturer    4N36-X000Optocoupler DC-IN 1-CH Transistor With Base DC-OUT 6-Pin PDIPVishay Semiconductors4N37-X000Optocoupler DC-IN 1-CH Transistor With Base DC-OUT 6-Pin PDIPVishay Semiconductors4N35-X000Optocoupler DC-IN 1-CH Transistor With Base DC-OUT 6-Pin PDIPVishay Semiconductors4N35 Environmental and Export ClassificationsAttributeDescriptionRoHS StatusROHS3 CompliantMoisture Sensitivity Level (MSL)1 (Unlimited)Where To Use 4N354N35 optocoupler can be used for variety of general purpose requirements in electronic circuits.

You can also use to detect voltage in AC and DC circuits, at the output of microcontroller Chips, controlling high power transistors, high voltage devices etc.How To Use 4N35Using 4N35 optocoupler is very easy, as discussed above the device contains two parts or components an IRLED and a Phototransistor, the LED Anode pin can be connected with the output of the device you are operating or working on (for example any IC or Microcontroller) and the cathode pin of the LED should be connected with the ground of that device, this LED should be handled same as you handle any other LED for example you have to use a current limiting resistor too. When the output of the device goes high the LED will become switched ON and the IR light with be detected by the photo transistor making it saturated or switched ON hence the collector and emitter pins will become shorted and as a result any wire connected with the pin 4 and 5 will be connected with each other. The internal phototransistor can also be controlled like a normal BJT transistor, the pin6 is connected with the base of the transistor and you can also use pin6 to control the transistor.How to Safely Long Run 4N35 in a Circuit4N35 Optocoupler ICFor long term stability and performance of this device it is recommended that the user should not operate the device above its max ratings. Do not apply or operate load of 150mA through this device. Using a current limiting resistor with IR LED is always recommended.
