Which outcome results when exceeding the maximum allowable reverse voltage in a silicon PN junction diode?

A)Avalanche breakdown causes reverse current
B)Recombination dominates depletion region current
C)Forward bias current linearly increases
D)Intrinsic carrier concentration severely decreases

💡 Explanation

Exceeding reverse voltage causes avalanche breakdown because high electric fields accelerate electrons, causing impact ionization, which creates more carriers; therefore, massive reverse current flows rather than gradual increase due to minority carriers.
