WebThyristors (SCR) and AC Switches. Designed for high immunity against glitches on mains and high load supplies, the Thyristors, also known as silicon-controlled rectifiers (SCR), triacs and logic-level gate ACS circuits are switches working on 120, 240 and 480 V AC power lines for appliances, tools, converters and drive systems. WebA thyristor is a 4 layer bipolar current controlled device having 3 terminals. A thyristor is basically designed to conduct a large current when it is on and block high voltage when it is in the off state. This means they can be switched on whenever there will be an appropriate control signal present at the gate terminal of the thyristor.
