BJT Computer Abbreviation

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). OR it is an P N junction formed active . Semiconductor device used for amplification of current.
