It has a decent gain value (hfe) of a maximum of 700 and is highly linear. It has been widely used in amplifier applications for pre-amplification purposes, in high-frequency circuits.  It is also used as oscillators with its complementary A733 PNP transistor. When used as a switch, it can be easily controlled by an MCU/MPU since it has a base voltage of only 5V. It can switch loads up to 50V but has a very low collector current rating of only 150mA, so this transistor is not a good choice to use as a switch. 2N2222 will be a better alternative for switching applications. However, this transistor is out of date and will not be readily available if you are in Asian or European countries. In that case, you can try the 2N3904 ON semiconductor transistor. Note: The C945 is a Japanese NPN transistor, so the pin out will be in Emitter, Collector, Base order. But the order for European transistors like BC546 will be like Emitter, Base and Collector. Usually during such replacements heat shrink tubes are used to cross over the Base and Collector pins without contacting them.2SC945 Pinout Pin NumberPin NameDescription1EmitterCurrent Drains out through emitter, normally connected to ground2CollectorCurrent flows in through collector, normally connected to load3BaseControls the biasing of transistor, Used to turn ON or OFF the transistor2SC945 FeaturesType - NPNCollector-Emitter Voltage: 50 VCollector-Base Voltage: 60 VEmitter-Base Voltage: 5 VCollector Current: 0.1 ACollector Dissipation - 0.25 WDC Current Gain (hfe) - 90 to 600Transition Frequency - 150 MHzNoise Figure - 0.8 dBOperating and Storage Junction Temperature Range -55 to +150 °CPackage - TO-922SC945 Absolute Maximum Ratings2SC945 MarkingSometimes the "2S" prefix is not marked on the package - the 2SC945 transistor might be marked "C945".2SC945 Marking Diagram2SC945 AlternativesAlternatives for 2SC945: BC546, 2SC1815, KSC945C2SC945 Replacement & EquivalentYou can replace the 2SC945 with the 2SC1815, 2SC2458, 2SC3198, 2SC3199, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, BC182LB, C1815, C945, H945, KSC1815, KSC945C, KTC3198 or KTC31992SC945 ApplicationsLow current switchesPre-amplifiersH-bridge circuits for low power motorsAudio frequency amplifier circuitsOscillator circuits2SC945 PackageComponent Datasheet2SC945 Datasheet

The metal casing has a hole in the middle – ideal for mounting it. What causes bridge rectifier failure?The common reasons for a diode failure are excessive forward current and a large reverse voltage. Usually, large reverse voltage leads to a shorted diode while overcurrent makes it fail open. What does a silicon bridge rectifier do?A Bridge rectifier is an Alternating Current (AC) to Direct Current (DC) converter that rectifies mains AC input to DC output. Bridge Rectifiers are widely used in power supplies that provide necessary DC voltage for the electronic components or devices. How does a bridge rectifier work?Bridge Rectifiers use four diodes that are arranged cleverly to convert the AC supply voltage to a DC supply voltage. The output signal of such a circuit is always of the same polarity regardless of the polarities of the input AC signal. The current will flow through the load resistor via the two forward-biased diodes. How do you know if you have a bad rectifier?You'll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery. When this happens, it's only a matter of time before the engine stops completely. What are the advantages of bridge rectifier?A bridge rectifier has a higher efficiency than a half-wave rectifier. But in some cases, the efficiency of the center-tapped full-wave rectifier and the bridge rectifier is the same. A smooth output is obtained from a bridge rectifier than the half-wave rectifier. Does a bridge rectifier increase voltage?As most bridge rectifiers use silicon diodes, this drop will be a minimum of 1.2 volts and will increase as the current increases. Accordingly the maximum voltage output that can be achieved is a minimum of 1.2 volts down on the peak voltage of the AC input. Which rectifier is more efficient?The bridge rectifier provides significant advantages over the half wave rectifier, allowing better smoothing and better efficiency. Although the half wave rectifier finds applications in signal and peak detection, it is not widely used in power rectification. How do you calculate the current output of a bridge rectifier?The current can be measured at the output of the secondary transformer coil and is usually available on the data sheet for the transformer. This value is measured in amperes, or amps. Multiply the current value, I, by the resistance value, R. Multiply the resulting number by 150%. What is the application of rectifier?A rectifier is a device that converts an oscillating two-directional alternating current (AC) into a single-directional direct current (DC). Rectifiers can take a wide variety of physical forms, from vacuum tube diodes and crystal radio receivers to modern silicon-based designs.

It comes with collector current 5A and is mainly used for switching and amplification purpose. The amplification factor is 60-400. This factor indicates the amount of current this device can amplify. How do PNP transistor?The PNP transistor is a type of transistor in which one n-type material is doped with two p-type materials. It is a device that is controlled by the current. Both the emitter and collector currents were controlled by the small amount of base current. Two crystal diodes are connected back-to-back in the PNP transistor. How do you test a transistor?Hook the positive lead from the multimeter to the to the BASE (B) of the transistor. Hook the negative meter lead to the EMITTER (E) of the transistor. For an good NPN transistor, the meter should show a voltage drop between 0.45V and 0.9V. If you are testing PNP transistor, you should see “OL” (Over Limit). Can I use PNP instead of NPN?Generally, the PNP transistor can replace NPN transistors in most electronic circuits, the only difference is the polarities of the voltages, and the directions of the current flow. PNP transistors can also be used as switching devices and an example of a PNP transistor switch is shown below. What does PNP and NPN mean?PNP = Switched Positive. NPN = Switched Negative. “Switched” refers to which side of the controlled load (relay, small indicator, PLC input) is being switched electrically.
