Which consequence results when exceeding a photodiode's reverse voltage?

A)Increased depletion region current
B)Photocurrent remains unchanged
C)Increased band-gap energy
D)Recombination rate is lowered

💡 Explanation

When reverse voltage is exceeds, there is increased depletion region current caused by impact ionization. Specifically, the avalanche effect occurs because accelerated electrons gain sufficient energy to excite new electron-hole pairs, therefore current rapidly increases because of this, rather than photocurrent leveling off.
