MHT CET Physics question

Not in JEE Advanced syllabus

A general purpose diode is more likely to suffer avalanche breakdown rather than zener breakdown because:

(A)its leakage current is small
(B)it has low reverse resistance
(C)it is lightly dopedCorrect
(D)it has strong covalent bond

Answer: (C)

Solution

A general purpose diode is lightly doped, so its depletion layer is wide and the field is not strong enough for Zener (field) breakdown, whereas carriers can gain enough
