Which is more widely used in the industry, NPN or PNP transistors?
Homework Answers
An NPN transistor has electrons as majority charge carriers. The PNP transistor has holes as the majority charge carriers. since the mobility of electrons is better than the mobility of holes. so as a result, NPN transistors are faster than pnp that's why they are preferred.
