Bipolar Junction Transistor

What is the function of Transistor?

• Amplification and switching

• Convert DC to AC

• Block the current flow

• Amplification and conversion

Name three (3) terminals of BJT

• Emitter, cathode, collector

• Anode, Emitter, Base

• Emitter, Base, Gate

• Emitter, collector, base

Saturation mode of biasing is when current is practically zero and use as an open switch in switching application.

• True

• False

In which modes does the BJT need to operate to be switched OFF?

• Active mode

• Saturation mode

• Cut off mode

In active mode of NPN operation, what happen to electron flow when not combine with holes in the base region?

• Most of the electrons will diffuse to collector region

• Most of the electron will diffuse back to emitter

• Some of the electron will diffuse to collector
