The effect that causes a sharp increase in reverse current when the reverse-bias voltage across a diode becomes excessive is called
A) doping
B) reverse bias
C) zener voltage
D) avalanche

Question

Quizplus · Accepted Answer

The avalanche effect occurs when the reverse-bias voltage across a diode becomes excessive, causing a sharp increase in reverse current. This happens because the high voltage gives free electrons enough energy to knock electrons off the atoms within the semiconductor material, creating more free electrons and holes, which in turn creates a large current.
