transistor base emitter collector identification 2n3055

Avalanche pulse generatorsĪs you can see on the datasheet below for the 2n2222a NPN transistor, the 'Collector-Emitter Saturation Voltage' and 'Base-Emitter Saturation Voltage' are defined respectively as 0.3 to 1.0 and 1.2 to 2.0. A diode can also perform these nonlinear functions but the transistor provides more circuit flexibility. the signal is applied, and where the a.c output is taken from the transistor.īecause base–emitter voltage varies as the logarithm of the base–emitter and collector–emitter currents, a BJT can also be used to compute logarithms and anti-logarithms. Just find out the terminals where the input a.c. One must be able to identify whether a given transistor is connected as a common emitter configuration, common collector or common base configuration. Collector – The section which collects the major portion of the majority charge carrier supplied by the emitter is called a collector. The emitter-base junction injects a large amount of majority charge carrier into the base because it is heavily doped and moderate in size. Offering a high i/p impedance & a low o/p impedance are commonly used as a buffer.The voltage gain of this transistor is unity, the current gain is high and the o/p The common collector transistor configuration is also known as the emitter follower because the emitter voltage of this transistor follows the base terminal of the transistor. Transistor Configuration – Common Base, Collector and Emitter.One is the Emitter-base junction, and the other is Collector- base junction. Thus, there are two junctions of the transistors.

Thus, as there are three terminals of the transistor, i.e. The transistor as its names suggests transfer resistance from one channel to other channels.
