Q. 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
Explanation
(b) Zener breakdown can occur in heavily doped diodes. In lightly doped diodes the necessary voltage is higher, and avalanche multiplication is then the chief process involved
