WebThis is the current to apply between gate and cathode (or gate and electrode A1 for Triac) to turn-on the device. This parameter defines the sensitivity of the component. For a SCR, the gate current has always to be sunk by the gate. For a TRIAC, IGT is define for 3 or 4 quadrants corresponding to the different polarities of A2, A1 and gate: WebThis page will discuss basic triacs and SCRs. A triac is a bidirectional, three-terminal dual, back-to-back Thyristor (SCR) switch. This device can switch the current in either direction by applying a small current of either polarity between the gate and main terminal two. The triac is fabricated by integrating two Thyristors in an inverse ...
