Which risk increases when a reverse-biased Zener diode's depletion region decreases?

💡 Explanation

Premature avalanche breakdown becomes more probable because decreased depletion width increases the electric field. This enhances the probability of quantum tunneling, because rather than impact ionization dominating, increased tunneling causes avalanche at lower voltages.
