Choose the correct statement about Zener diode

View answer and explanation

Correct option: D

It works as a voltage regulator in reverse bias and behaves like simple pn junction diode in forward bias.

The correct answer is It works as a voltage regulator in reverse bias and behaves like simple pn junction diode in forward bias because Zener diodes are designed to operate in reverse breakdown.
