In a thyristor holding current is
WebA basic thyristor is a 4-layer device with two terminals: ___ and ___. pnpn. Thyristors: It is constructed of four semiconductor layers that form a ___ structure. forward voltage. Thyristors: It acts as a switch and remains off until the ___ reaches a certain value, turns on, and conducts. Conduction. Web2-Holding Current I H This is the minimum anode current required to maintain the thyristor in the on state. To turn off a thyristor, the forward anode current must be reduced below its holding current for a sufficient time for mobile charge carriers to vacate the junction. If the anode current is not maintained below I H for long enough, the
