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

Question:

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

1. lightly doped and have wide depletion layer.

2. heavily doped andhave narrow depletion layer.

3. heavily doped and have wide depletion layer.

4. lightly doped and have narrow depletion layer.

Correct Option: , 2

Solution:

(2)

The zener breakdown occurs in the heavily doped $\mathrm{p}-\mathbf{n}$ junction diode. Heavily doped $\mathrm{p}-\mathbf{n}$ junction diodes have narrow depletion region.
