Which risk increases significantly when applying reverse bias to semiconductors?

A)Avalanche breakdown damages the structure
B)Zener tunneling creates high current
C)Ohmic loss diminishes efficiency badly
D)Transistor saturation stops all transistor actions

💡 Explanation

Avalanche breakdown damages the gate oxide integrity because impact ionization increases exponentially in depletion region; therefore, substantial reverse current leads to permanent damage rather than controlled Zener behavior under lower voltages.
