WebFeb 24, 2012 · Holding Current of Thyristor. This is the rating of current below, which anode current must fall to turn off the device. Gate Specification of SCR Gate Current to Trigger (I GT) This is the value of gate current below which device cannot be turned on. This value of current specified at a particular forward break down voltage. WebLike the diode, the Thyristor is a unidirectional device, that is it will only conduct current in one direction only, but unlike a diode, the thyristor can be made to operate as either an …
