WebThe electrons in the base are called minority carriers because the base is doped p-type, which makes holes the majority carrier in the base. In an npn transistor, the majority charge carriers in base is holes and minority charge carriers are electrons. NPN Transistor: Most Upvoted Answer WebFor instance, a PNP transistor functions by injecting holes into the base, where they are the minority carrier whereas an NPN transistor injects electrons into the base. Holes are a minority carrier when they are in an n-type material, and electrons are a minority carrier when they are in a p-type material.

WebHowever, the minority current electrons (as you will see later) play the most important part in the operation of the NPN transistor. These minority carriers actually conduct the current for the reverse-biased junction when electrons from the P material enter the N material, and the holes from the N material enter the P material.
