WebBut, the main classification of transistors is as follows: In the next few sections, let us study these transistors in detail. Bipolar Junction Transistor. A bipolar junction transistor, shortly termed as BJT is a current controlled device that consists of two PN junction for its function. It is configured in two ways as NPN and PNP. Web25 de mar. de 2024 · What is a PNP Transistor. A PNP transistor is a bipolar junction transistor constructed by sandwiching an N-type semiconductor between two P-type semiconductors. A PNP transistor has three terminals – a Collector (C), Emitter (E) and Base (B). The PNP transistor behaves like two PN junctions diodes connected back to …
