TRIAC: What is it? (Definition, Operation & Applications)

WebA TRIAC has 3 terminals MT1, the gate and MT2 thyristors that use alternative symbols. You wire them in inverse parallel, you can then control them using a one-gate terminal. Current is then transmitted in whichever direction you choose, whether to MT1 or MT2 terminals which is then used in controlling AC power. WebThirdly, the power handling capacity of TRIAC is higher compared to DIAC. Also, you need to apply a negative or positive voltage at the gate terminal to initiate a TRIAC. But you can trigger a DIAC by adding a voltage across its terminals—equal to or more than its break …
