Question: Question no 01 a) What are the majority carriers in the base region of a npn transistor called? Explain the purpose of a thin, lightly doped base region. Why is the base current in a transistor so much less ... 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.

WebElectrons are the majority carrier. Because the emitter in npn transistor is n-type it has electrons as majority carriers, which pass through the base to the collector side. WebApr 10, 2024 · In an NPN transistor electrons are the majority charge carriers, whereas in a PNP the majority charge carriers are the holes, because of this the NPS transistors have faster recovery time when compared to the PNP type. It leads to the NPN having a very small switch ON and Switch OFF time, therefore offering a very high switching speed.

Webmajority carriers, in the cases where the majority carriers greatly outnumber the minority carriers. In other words, minority holes diffuse with Dn and electrons with Dp! zThe minority diffusion length is a function of the ambipolar diffusion constant for the minority carriers, as well as the variability in the lifetime, etc.
