1.	Zener breakdown takes place ifA. Doped impurity is lowB. Doped impurity is highC. Less impurity in `N`-partD. Less impurity in `P`-type
Answer» Correct Answer - B Zener breakdown can occure in heavily doped diodes. In lightly doped diodes the necessary voltage is higher, and avalanche multiplication is then the cheif process involved.
