WebThe minority charge carrier of the NPN transistor is the hole and in PNP transistor it is electrons. The switching time of NPN transistor is more as compared to PNP transistor because the majority charge carrier of NPN transistor is an electron. The emitter-base junction of both the NPN and PNP transistor is connected in forward biased. WebOn the contrary, the collector and emitter has holes as minority charge carrier while the base has electrons as minority charge carriers. The base is a thin P-Type layer having the majority of holes. Applying a positive voltage with respect to the emitter will push electrons in the base (p-region).
