The value of anode current required to maintain the conduction of an SCR even though the gate signal is removed is called as the

(a) holding current

(b) latching current

(c) switching current

(d) peak anode current

This question was addressed to me by my college director while I was bunking the class.

I would like to ask this question from Thyristors-2 topic in chapter Power Electronics Devices of Power Electronics

Correct option is (b) latching current

Easiest explanation: It is the minimum anode current value required to maintain the conduction of an SCR even though the gate signal is removed. It is a very important parameter when employing an SCR in any circuit.
