Glossary Definition for Bipolar Junction Transistor

Glossary Term: Bipolar Junction Transistor 


A Bipolar Junction Transistor, or BJT, is a solid-state device in which the current flow between two terminals (the collector and the emitter) is controlled by the amount of current that flows through a third terminal (the base).

Contrast to the other main transistor type, the FET, in which the ouput current is controlled by input voltage (rather than by input current).
