WebTherefore, the NPN transistor has higher switching speed as compared to the PNP transistor. Majority Charge Carriers The current flow in a transistor depends on the majority charge carrier. Therefore, the majority charge carriers in NPN are electrons while in PNP transistor is Holes. Base Current WebIn NPN transistors, the primary charge carriers are electrons. In PNP transistors, the primary charge carriers are holes. PNP Transistor A PNP transistor can be though of as two PN junction diodes, with the p-doped sides of each facing outwards and having a shared n-type region between them.
