Question:

Zener breakdown takes place if –

Options:

Doped impurity is low

Doped impurity is high

Less impurity in N-part

Less impurity in P-part

Correct Answer:

Doped impurity is high

Explanation:

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.
