Zener breakdown takes place if

A

doped imputy 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 occur in heavily doped diodes. In highly doped diodes the neccesary voltage is higer and avalanche multiplication is the main process.
