It is designed for AC load switching where inductive kickback would otherwise require an external RC snubber. The Snubberless construction handles high dV/dt commutation without that network, saving two passives and a board trace. The 35 mA maximum gate trigger current (Igt) and 1.3 V Vgt mean a standard logic-level driver or optotriac can fire it directly. Holding current is also 35 mA, so the load must draw at least that to keep the triac latched — relevant for low-wattage fans or small transformers that may drop below that threshold during a brownout. D2PAK (TO-263-3) footprint. Active status with ROHS3 compliance. Snubberless series from ST. For a lower-current variant in the same family, the T1235-600G is a 12 A alternistor with the same 600 V rating and Snubberless construction. It shares the same D2PAK footprint and gate-drive requirements, making it a drop-in for lighter loads without requalifying the PCB layout.","metaTitle":"STMicroelectronics T1635-600G-TR Snubberless Triac","metaDescription":"ST T1635-600G-TR alternistor triac: 600 V off-state, 16 A RMS, 35 mA Igt, Snubberless, D2PAK SMT.
