Did you know?
The thyristor is a four-layered, three-terminal semiconductor device, with each layer consisting of alternating N-type or P-type material, for example P-N-P-N. The main terminals, labelled anode and cathode, are across all four layers. The control terminal, called the gate, is attached to p-type material near the cathode. (A variant called an SCS—silicon controlled switch—brings all four layers out t… WebHolding current :-It is the minimum anode current to maintain the thyristor in the on-state (if the forward anode current is reduced below holding current , a depletion region develops around junction J2 due to the reduced number of carriers and the thyristor is in blocking state). Latching current >Holding current 47 Sponsored by Oldehealth
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 WebThis current is associated with the turn-on process of the thyristor. Its value is somewhat twice or thrice the holding current. Holding current: Holding current is that minimal current that flows through the device in forward condition but below this particular value the device stops conduction. This current is related to turn off the process ...
