It is designed for AC load switching where inductive kickback would otherwise demand an external RC snubber — the Snubberless™ construction handles high dV/dt commutation internally. Typical applications include solid-state relays, motor speed controllers, heating elements, and lighting dimmers in industrial and appliance environments.","metaTitle":"STMicroelectronics T1235H-6I Triac, Snubberless™, 600V, 12A","metaDescription":"STMicroelectronics T1235H-6I Snubberless™ triac, 600V off-state, 12A RMS, TO-220 through-hole.
