Which of the following diode is used in ultra-high speed switching electronic circuits?

A)

Zener diode

B)

Schottky diode

C)

Varactor diode

D)

Tunnel diode

Correct Answer : Option (D) : Tunnel diode

Explanation : Due to tunneling, a large number of electrons penetrate through the junction, so a large amount of current is produced. And as we are considering a special diode, we can control its I-V characteristics to improve the switching speed.
