A PNP transistor is made up of a doped N-Type material that is sanduzied in between two P-Type materials. In a PNP transistor holes are the majority charge carrier that means the holes are emitted by the collector and collected by the emitter, the main difference between the NPN and PNP transistor is the flow of electrons runs from collector to emitter but in a PNP transistor the electrons run from emitter to collector, as a result, a PNP transistor turns on when there is a low or 0V on the base of the transistor. Where an NPN transistor is on when a positive or high signal is applied. Featured By RoboticsBD.
