    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-part

    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.
