Q. Avalanche breakdown is due to
A) Collision of minority charge carrier
B) Increase in depletion layer thickness
C) Decrease in depletion layer thickness
D) None of these
Explanation
(a) At high reverse voltage, the minority charge carriers acquire very high velocities. These by collision break down the covalent bonds, generating more carriers. This mechanism is called Avalanche breakdown
