Question: Zener breakdown takes place if
[RPMT 2000]
Options:
A) Doped impurity is low
B) Doped impurity is high
C) Less impurity in N-part
D) Less impurity in P-type
Show Answer
Answer:
Correct Answer: B
Solution:
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.
