What is the reverse recovery current of diodes?

The charge flowing during reverse recovery time is called “reverse recovery charge”. When switching from the conducting to the blocking state, a diode or rectifier has stored charge that must first be discharged before the diode blocks reverse current.

Similarly one may ask, what is reverse current in a diode?

A very small amount of current (on the order of nA) – called reverse saturation current – is able to flow in reverse through the diode. Breakdown: When the voltage applied across the diode is very large and negative, lots of current will be able to flow in the reverse direction, from cathode to anode.
