Question

Reverse recovery time for a diode is?

(a) Time taken to eliminate excess minority charge carriers

(b) Sum of storage time (TS) and transition time (TT)

(c) Time taken to eliminate excess majority charge carriers

(d) Time elapsed to return to non conduction state

I had been asked this question during an interview for a job.

My query is from PN Diode Switching Times topic in division Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

Right option is (a) Time taken to eliminate excess minority charge carriers

Best explanation: The time period for which diode remains in conduction state even in reverse direction is called storage time. The time elapsed to return the non conduction state is called transition time. Their sum is called reverse recovery time.
