1.	Zener breakdown in a semi-conductor diode occurs whenA. Forward current exceeds certain valueB. Reverse biase exceeds certain valueC. Forwads biase exceeds certain valueD. Potential barrier is reduced to zero
Answer» Correct Answer - B When reverse biase is increased, the electric field at the junction also increases. At some stage the electric fields breaks the covelent bond, thus the large number of charge carriers are generated. This is called Zener breakdown.
