It is a general-purpose PNP transistor that can be used in electronic circuits as a switch or amplifier. Its HFE ratings range from 125 to 800, making it an ideal transistor for use as a small signal amplifier in electronic circuits such as audio signal amplification. The HFE ratings of BC557 can be determined by the last letter after its number, for example, BC557A HFE ratings range from 110-220, BC557B HFE ratings range from 200-450, and BC557C HFE ratings range from 420-800. The maximum collector dissipation is 500 milliwatt, which is another advantage for using it in amplification stages. Furthermore, it will perform well when used as a switch for loads less than 100mA. The transistor also has a good collector to emitter (VCE) value of -45V, so it can be used in circuits requiring 40 to 45 volts DC.BC557 PinoutBC557 transistorBC557 transistor pinout Pin NumberPin NameDescription1CollectorCurrent flows in through collector2BaseControls the biasing of transistor3EmitterCurrent Drains out through emitterBC557 FeaturesBi-Polar PNP TransistorDC Current Gain (hFE) is 300 maximumContinuous Collector current (IC) is 100mAEmitter Base Voltage (VBE) is 6VBase Current(IB) is 5mA maximumAvailable in To-92 Package BC557 ParameterPackage / Case:TO-226-3 TO-92-3 (TO-226AA)Base Product Number:BC557Supplier Device Package:TO-92-3Transistor Type:PNPVce Saturation (Max) @ Ib Ic:650mV @ 5mA 100mACurrent - Collector Cutoff (Max):15nA (ICBO)DC Current Gain (hFE) (Min) @ Ic Vce:110 @ 2mA 5VCurrent - Collector (Ic) (Max):100mAVoltage - Collector Emitter Breakdown (Max):45VBC557 EquivalentBC557 PNP equivalent transistor: BC157, BC558, 2N3906, 2SA1943, BD140, S8550, TIP127, TIP42NPN Complementary: NPN Complementary of BC557 is BC547The output pins of some equivalents are different please see pinout details of the equivalent transistor before replacing in the circuit.BC557 Working PrincipleIn PNP transistors, holes are the majority carriers, whereas in NPN transistors, electrons are the majority carriers. Although holes are the majority carriers, the base terminal is still important in the overall operation of the transistor. In the NPN case, holes are emitted from the emitter instead of electrons, and they are collectors via the collector terminal.BC557 StructureBC557 is known as a current controlled device because the small current present at the base side is used to control the large current present at the remaining terminals. Remember that when the transistor is turned off, there is a current at the base terminal, whereas when the transistor is turned on, there is no current at the base terminal.Where & How to use BC557Because the BC557 is a general purpose transistor, it can be used in a wide range of general purpose applications, such as audio amplifiers in small radios, electronic buzzers, electronic bells, and other sound circuits that require low amplification. This transistor can also be used in audio preamplifier stages due to its high gain. Aside from these applications, this transistor can also be used as a switch in electronic applications for a 100mA load, switching any part of an electronic circuit, other high-power transistors, LEDs, relays, and so on.How to safely long run BC557 in a circuitTo safely run this transistor for good performance for a long time in your electronic circuit, do not operate it at -45V DC, always use a suitable base resistor, do not provide this transistor with more than -100mA load, the operating and storage temperature around the transistor should be between -65 and +150 degrees Celsius, and always check the transistor's pinout before placing it in the circuit.BC557 Typical Application1. BC557 Transistor as switch When a transistor is used as a switch, it operates in the Saturation and Cut-Off Regions, as previously explained. As previously stated, a transistor will act as an open switch during forward bias and as a closed switch during reverse bias; this biasing can be accomplished by supplying the necessary amount of current to the base pin. As mentioned, the biasing current should be limited to a maximum of 5mA. Anything more than 5mA will destroy the transistor, so a resistor is always connected in series with the base pin. The resistor (RB) value can be calculated using the formula below: RB  = VBE / IB Where, the value of VBE should be 5V for BC557 and the Base current (IB depends on the Collector current (IC). The value of IB should not exceed mA. 2. BC557 Transistor as Amplifier When in the active region, a transistor acts as an amplifier. It has the ability to amplify power, voltage, and current in a variety of configurations. Some of the configurations used in amplifier circuits are: Common emitter amplifierCommon collector amplifierCommon base amplifier The most common and widely used configuration among the aforementioned emitter types is the common emitter type. The DC current gain of a transistor when used as an amplifier can be calculated using the following formula: DC Current Gain = Collector Current (IC) / Base Current (IB)BC557 PackageBC557 ApplicationPreamplifierSmall signal audio amplifierDriving Loads under 0.1mA or 100mAAny general purpose application that comes under its ratings.BC557 ManufacturerON Semiconductor (Nasdaq: ON) is driving energy efficient innovations, empowering customers to reduce global energy use.

IntroductionThe LM741 series are general-purpose operational amplifiers. It is intended for a wide range of analogue applications. The high gain and wide range of operating voltage provide superior performance in integrator, summing amplifier, and general feedback applications. This article will introduce the circuit of capacitance measurement composed of LM741.CatalogIntroductionCatalogI Circuit DesignFAQOrdering & QuantityI Circuit DesignAs Figure 1 shows, the measuring principle of this circuit is: a triangular wave is formed from the process of charging and discharging of measured capacitor Cx. And the capacitance can be measured by the oscillation period of the triangular wave. A Miller integrating circuit consists of A1. A Schmidt circuit consists of A2 and the Schmidt circuit forms positive feedback and generates oscillation. Its amplitude is determined by R4 and R3, equal to 1 / 3 of the supply voltage. The charging current of Cx is determined by the supply voltage and R2, and the discharge current is determined by the supply voltage and R1 + R2. In principle, the oscillation period should not be affected by the supply voltage. However, due to the limitation of A2 differential input voltage and the constant of transistor driving circuit, it is not allowed to change the supply voltage greatly. The range of power supply voltage  is ±13 to ±15V. The absolute values of positive and negative supply voltages need to be equal. When the capacitor Cx is not connected, A2 oscillates with a delay of about 20 μS, and Cx can be calculated to compensate for this. The measurement time is 10S when the Cx capacitance is 1000μF. If R1 and R2 use 1KΩ resistance, the measurement time can be shortened to 1/10.Circuit output U. The capacitance can be read out by connecting a external counter.Figure 1. capacitance measurement circuitLM709 forms a positive feedback through R7 and VT2 to the negative input to form a Schmidt trigger. When LM709 outputs a high level, VT2 is saturated and turned on, and the voltage of C pole of VT2 is 0V. Both VT3 and VT1 are cut off. The +15V power supply charges Cx through R1 and R2, and the output voltage of the LM741 gradually decreases. When it drops to 0V, Schmidt reverses and the output voltage goes low (-15V). At this time, VT2 is cut off, and the voltage of C pole of VT2 rises to +5V, consolidating the low-level output state of LM709. At the same time, VT3 and VT1 get the base current and turn on. The CX is reversely charged via R2 and -15V power supplies. The output voltage of LM741 increases gradually. When it rises to + 5V, Schmidt reverses again and the output becomes high level. Then a cycle complete. The above process is repeated to form periodic oscillations.FAQWhat is lm741 op amp?An LM741 operational amplifier is a DC-coupled high gain electronic voltage amplifier. It has only one op-amp inside. An operational amplifier IC is used as a comparator which compares the two signal, the inverting and non-inverting signal.Why Opamp is called 741?The 741 Op Amp IC is a monolithic integrated circuit, comprising of a general purpose Operational Amplifier. It was first manufactured by Fairchild semiconductors in the year 1963. The number 741 indicates that this operational amplifier IC has 7 functional pins, 4 pins capable of taking input and 1 output pin.How does a 741 op amp work?The most common Op-Amp is the 741 and it is used in many circuits. The OP AMP is a 'Linear Amplifier' with an amazing variety of uses. Its main purpose is to amplify (increase) a weak signal - a little like a Darlington Pair. The OP-AMP has two inputs, INVERTING ( - ) and NON-INVERTING (+), and one output at pin 6.How do you calculate lm386 gain?Voltage Gain Analysis:Without any external components, it has a gain of Gv = 2x15K/(150+1350) = 20 (26 dB).With a capacitor (or shortcutting) between pins 1 and 8 , it has a gain of Gv = 2x15K/150 =200 (46dB).Why does the IC 741 require dual power supply?Operational amplifiers have two power supply rails because they usually need to swing bipolar - output voltages that go either positive or negative in response to the normal range of input signals. ... Without the dual supplies the output signal would clip at the ground potential.How do I check my 741 IC?Testing a 741 ICThe circuit is commonly called as voltage follower. A voltage is applied to pin3 of the op-amp through the variable resistor (10K). All we need to do is to verify whether the voltages V1 and V2 are exactly same or not. Check them using a multi-meter.What is IC 741?An op amp is a complex electronic device, which consists of resistors, capacitors, transistors and diodes. It is commercially available in integrated circuit form. Most commonly available and used op amp IC is IC 741. The IC 741 is a small chip. It comprises eight pins.What is gain bandwidth product of 741?Gain-Bandwidth Product: For an Op-Amp the gain, G is defined as the gain when a signal is fed differentially into the op-amp and no feedback loop is present. ... It is generally given in V/μs, and for the 741 op-amp is something close to 1v/μs.What are the features of IC 741?Short circuit and overload protection provided.In theory, the dc output voltage will be zero if both the inputs of the 741 IC are connected to the ground. …Low power consumption.Large common mode rejection ratio (CMRR) and differential voltage ranges.No external frequency compensation is required.Which op-amp (LM356 or LM741) is the better choice for higher frequency applications?Um, the LM356 is an audio power amplifier with a 300 KHz bandwidth. The LM741 is an operational amplifier with a typical unity gain bandwidth of 1 MHz.In other words, they are entirely different sorts of things and not at all interchangeable.Neither is very good at higher frequencies.You might be thinking of the LF356, which is a JFET input operational amplifier with a unity gain bandwidth around 5 MHz. Much better part in almost every dimension than the LM741.Can we use an LM324 instead of an LM741 for constructing an op-amp integrator?Yes. It will likely perform slightly better too as it has a slightly better specification (frequency, slew rate, etc), plus you get four identical op amps in a single 14 pin package.
