In a npn transistor the current carriers are
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 WebOne of the major differences between NPN and PNP transistor is that in NPN transistors, electrons are the majority carriers, hence electrons are responsible for current flow. While, in PNP transistors, holes are the …

WebFeb 27, 2024 · The differences between NPN and PNP transistors are as mentioned in the following table given below: NPN Transistor. PNP Transistor. It has two N-type transistors. It has two P-type transistors. Its current points in the outward direction. Its current points in the inward direction. In it, the electron works as a major current carrier. WebMar 25, 2024 · A PNP transistor is a bipolar junction transistor constructed by sandwiching an N-type semiconductor between two P-type semiconductors. A PNP transistor has …
WebThe main difference between the two types of transistors is that holes are the more important carriers for PNP transistors, whereas electrons are the important carriers for NPN transistors. Then, PNP transistors use a small base current and a negative base voltage to control a much larger emitter-collector current.
WebApr 10, 2024 · The transistor is a three-terminal current control device, that can be used to create complex electronic circuits. Even though there are other types of transistors, Bipolar Junction Transistors (BJT) are still popular and used everywhere. So, we will discuss about BJTs and then difference between NPN and PNP transistors. WebThis voltage source needs to exceed 0.6 V for majority carriers (electrons for NPN) to flow from the emitter into the base becoming minority carriers in the P-type semiconductor. If …
