A TRIAC is a bidirectional, three-electrode AC switch that allows electrons to flow in either direction. It is the equivalent of two SCRs connected in a reverse-parallel arrangement with gates connected to each other. A TRIAC is triggered into conduction in both directions by a gate signal like that of an SCR. … See more Although TRIACs and SCRs look alike, their schematic symbols are dissimilar. The terminals of a TRIAC are the gate, terminal 1 (T1), and terminal 2 … See more The characteristics of a TRIAC are based on T1 as the voltage reference point. The polarities shown for voltage and current are the polarities of T2 with respect to T1. The polarities shown … See more TRIACs block current in either direction between T1 and T2. A TRIAC can be triggered into conduction in either direction by a momentary positive or negative pulse supplied to the gate. If the appropriate signal is … See more TRIACs are often used instead of mechanical switches because of their versatility.
