WebOct 25, 2024 · October 25, 2024. · Ajay Dheeraj. NPN transistor is a three-terminal device having a p-type semiconductor sandwiched between the two n-type semiconductors. It is the most useful of the two bipolar junction devices. The other being the PNP transistor. It has various applications and is used mostly for amplification and switching. WebAnd that's exactly what transistors do: in an NPN transistor, the Emitter region dumps large numbers of electrons into the p-doped Base. From the viewpoint of the CB junction, those electrons are on the wrong side of that …
