In which of these is reverse recovery time nearly zero?

[A]. Zener diode
[B]. Tunnel diode
[C]. Schottky diode
[D]. PIN diode

Answer: Option C


In schottky diode there is no charge storage and hence almost zero reverse recovery time.

Schottky diode has no P-N junction, hence no depletion layer thats why no charge storage.

Diode is unipolar or bipolar?

Both bipolar diodes and uni polar diodes exists.

PN junction diode is bipolar as conduction is due to both holes and electrons.

The Schottky diode is uni polar as conduction is only due to only one carrier.

What is reverse recovery time?

When switching from the conducting to the blocking state, a diode or rectifier has stored a charge that must first be discharged before the diode blocks reverse current. This discharge takes a finite amount of time known as the Reverse Recovery Time.
