Maximum gate trigger current is 35 mA, and the gate trigger voltage tops out at 1.5 V. That is a standard-sensitivity triac — it needs a modest driver stage, typically a logic-level transistor or an optotriac with a series resistor. The 20 mA maximum holding current means the triac will stay latched once triggered as long as the load current stays above that threshold; below 20 mA it will commutate off. For low-power loads like a small fan or a relay coil, check that the load current exceeds the hold level at all points in the cycle, or the triac may drop out prematurely.
Rework and mounting
TO-220AB through-hole package with three leads and a metal tab. The tab is electrically connected to the middle pin (MT2); use an isolated mounting interface if bolting to a grounded heatsink.
