MCQ Practice Question

Electronic Devices & Circuits PN Junction Diode

Reverse recovery time of a PN diode is mainly associated with?

ARemoval of stored charge when switching from forward conduction to reverse blocking
BTime required to heat the package
CForward voltage becoming exactly zero
DZener voltage regulation only

Correct Answer: A. Removal of stored charge when switching from forward conduction to reverse blocking

Explanation: After forward conduction, stored minority-carrier charge must be removed before the diode fully blocks reverse current, producing reverse recovery time.
