Question

Zener breakdown occurs in a p-n junction having p and n both:

Options

• lightly doped and have wide depletion layer.

• heavily doped and have narrow depletion layer.

• lightly doped and have narrow depletion layer. 

• heavily doped and have wide depletion layer.

Answer 1

heavily doped and have narrow depletion layer.

Explanation:

Since the p-n diode in a Zener diode is heavily doped, its depletion layer is relatively thin.
