WebFigure 9. A Darlington TRIAC for high sensitivity with high holding current 2.3 Combining characteristics We have seen that the more sensitive the TRIAC (lower IG), the lower the value of the holding current, IH. Now, in certain applications a sensitive TRIAC with a high holding current, I H (or IL), may be required. WebA triac is a three-terminal (MT1, gate, and MT2) solid-state thyristor that uses the alternative symbols in Figure 1 and acts like a pair of SCRs wired in inverse parallel and controlled via a single gate terminal. It can conduct current in either direction between its MT1 and MT2 terminals and can thus be used to directly control AC power.
