Zener breakdown takes place if

A

Doped impurity is low

B

Doped impurity is high

C

Less impurity in `N`-part

D

Less impurity in `P`-type

Text Solution

Verified by Experts

The correct Answer is:
B
Zener breakdown can occure in heavily doped diodes. In lightly doped diodes the necessary voltage is higher, and avalanche multiplication is then the cheif process involved.
