MHT CET 2026 Physics question

Not in JEE Advanced syllabus

For a p-n junction diode, breakdown voltage occurs when

(A)reverse bias is decreased
(B)reverse bias is not changed
(C)reverse-bias is increasedCorrect
(D)forward bias is increased

Answer: (C)

Solution

When a p-n junction is reverse biased, only a tiny leakage current flows (minority carriers). As the reverse voltage is increased, the electric field in the depletion layer rises, and at a particular voltage (the breakdown voltage) the junction breaks down through avalanche or Zener
