Question

It will be correct to say that,

(1) A lightly doped diode has a thin depletion layer and a higher breakdown voltage

(2) A heavily doped diode has a thin depletion layer and a lower breakdown voltage

(3) A lightly doped diode has a wide depletion layer and a lower breakdown voltage 

(4) A heavily doped diode has wide depletion layer and a higher breakdown voltage 

Answer 1

Correct option: (2)

Explanation:

The width of the depletion layer, as well as the barrier potential across the junction, both decrease with an increase in the extent of doping, of the p and n sides, of the p–n junction diode.
