Transistor

5.3

Transistor

A three-terminal semiconductor device used to regulate current or to amplify an input signal into a greater output signal.

Transistors are also used to switch electronic signals.

Two types of transistors:

PNP-type transistor
- The arrow on the emitter (E) is drawn inward the base (B).
NPN-type transistor
- The arrow on the emitter (E) is drawn out of the base (B).
