Avalanche breakdown is due to

Question

Avalanche breakdown is due to (A) Collision of minority charge carriers (B) Increase in depletion layer thickness (C) Decrease in depletion layer thickness (D) None of these

Tardigrade Admin · Accepted Answer

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.
