JEE Main & Advanced Physics Semiconducting Devices Question Bank Semiconductor Diode

  • question_answer
    Zener breakdown takes place if                              [RPMT 2000]

    A)            Doped impurity is low      

    B)            Doped impurity is high

    C)            Less impurity in N-part    

    D)            Less impurity in P-type

    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.
