WebMay 8, 2016 · A TRIAC can turn on when there is a voltage across it and if a current can flow through it. If the current stops, the TRIAC will turn itself off. This is what happens at the mains zero crossing point. The current drops to zero as the voltage switches polarity and the TRIAC turns off by itself. WebFeb 28, 2024 · As the TRIAC is a bidirectional device, its VI characteristics curve will be in the first and third quadrants of the graph, similar to a Thyristor's VI characteristics. When terminal MT2 is configured to be positive in relation to terminal MT1, the TRIAC will operate in forward blocking mode.
