MHT CET 2023 Physics question

On increasing the reverse bias to a large value in a P-N junction diode, current

(A)increase slowly
(B)remains fixed
(C)suddenly increasesCorrect
(D)decreases slowly

Answer: (C)

Solution

In reverse bias only a small reverse saturation current (due to minority carriers) flows, and it remains nearly constant as the reverse voltage is raised. When the reverse bias reaches a large critical value, the breakdown voltage, the junction undergoes breakdown (Zener breakdown due to field emission
