triac, the values of latching current (IL), holding current (IH) and gate trigger current (IGT) vary slightly between the different operating quadrants. In general, for any triac, the latching current is slightly higher in the second (MT2+, G-) quadrant than the other quadrants, whilst the gate trigger

Triac. A triac can be regarded as a "bidirectional thyristor" because it conducts in both directions. For standard triacs, current flow in either direction between the main terminals MT1 and MT2 is initiated by a small signal current applied between MT1 and the gate terminal.

alternating current in a load. Triac is an abbreviation for triode a.c. switch. ‘Tri’– indicates that the device has three terminals and ‘ac’ means that the device controls alternating current or can conduct current in either direction. The key function of a triac may be understood by referring to the simplified Fig 7
