Web13 sep. 2024 · Switching time is faster in NPN & slower in PNP. NPN turns ON when the electron enters the base region. Whereas, PNP transistor turns ON when holes enter the base terminal. In both the transistors, the emitter-base junction is forward biased and the collector-base junction is reverse biased. WebThe behavior of a PNP transistor is completely analogous to that of an NPN transistor, except that positive and negative charge carriers are interchanged and the EBJ is forward-biased from emitter to base rather than from base to emitter.
