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 open-circuit switch or as a rectifying diode depending upon how the thyristors gate is triggered. In other words, thyristors can operate only in the switching ... WebTRIAC and SCR . TRIAC, from triode for alternating current, is a genericized trade name for an electronic component that can conduct current in either direction when it is triggered (turned on), and is formally called a bidirectional triode thyristor or bilateral triode thyristor.. TRIACs are a subset of thyristors and are closely related to silicon-controlled rectifiers …
