9/25/2023 0 Comments Transistor biased in active region![]() This time the Emitter is connected to the supply voltage V CC with the load resistor, RL which limits the maximum current flowing through the device connected to the Collector terminal. The voltage sources are connected to a PNP transistor are as shown. So for a PNP transistor to conduct the Emitter is always more positive with respect to both the Base and the Collector. The voltage between the Base and Emitter ( V BE ), is now negative at the Base and positive at the Emitter because for a PNP transistor, the Base terminal is always biased negative with respect to the Emitter.Īlso the Emitter supply voltage is positive with respect to the Collector ( V CE ). The construction of a “PNP transistor” consists of two P-type semiconductor materials either side of an N-type material as shown below. In other words for a PNP transistor, the Emitter is more positive with respect to the Base and also with respect to the Collector. Then, PNP transistors use a small base current and a negative base voltage to control a much larger emitter-collector current. The main difference between the two types of transistors is that holes are the more important carriers for PNP transistors, whereas electrons are the important carriers for NPN transistors. This produces a Positive- Negative- Positive type of configuration, with the arrow which also defines the Emitter terminal pointing inwards in the PNP transistor symbol.Īlso, all the polarities for a PNP transistor are reversed which means that it “sinks” current into its Base as opposed to the NPN transistor which “sources” current through its Base. Can you explain this answer? tests, examples and also practice Electronics and Communication Engineering (ECE) tests.Basically, in this type of PNP transistor construction, the two interconnected diodes are reversed with respect to the previous NPN transistor. and the collector currents is IC = 27 μA. ![]() Can you explain this answer? theory, EduRev gives you anĪmple number of questions to practice In bipolar transistor biased in the forward-active region the base current is IB=50 μA.
