Question

A zener breakdown occurs in a zener diode when

• A. it is forward biased and electric field intensity decreases beyond a certain value
• B. it is reverse biased and electric field intensity exceeds a certain value
• C. potential barrier is reduced to zero
• D. forward current exceeds certain value

Answer 1

Answer: (B)

Zener breakdown occurs in zener diode when reverse biased voltage applied to the diode is increased beyond a certain level which results in generating strong electric field
