Gate turn-off thyristor gto
WebSummary. A gate turn-off switch (GTO) is a four-layer p-n-p-n device similar in construction to an SCR. A GTO is triggered into conduction by applying a forward bias to its gate and turned off by the application of a reverse-gate bias. An SCR, on the other hand, is turned off primarily by reducing or reversing the anode current. WebGate Turn Off Thyristors V DRM (V): 1400, 1700, 2000, 2500, 4500. V RRM (V): 18, 100, 1400, 2000.
