WebNov 26, 2024 · Introduction to Triac: The TRIAC Symbol TRIAC construction A TRIAC has three terminals viz MT1, MT2, and G, and is a five-layer semiconductor device. It is a switching device similar to SCR(Silicon Controlled Rectifier). Still, it can conduct in both directions since it is made by combining two SCR in an anti-parallel state. WebTo switch-on an SCR, Triac, ACS or ACST, a gate current must be applied on its gate pin (G). The gate current flows between Gate (G) and Cathode (K) for SCR, or between Gate and terminal A1 for Triac, or between Gate and terminal COM for ACS and ACST. For Triac and ACST, the gate current could be positive or negative. Figure 1 illustrates the
