The Snubberless™ construction means it switches inductive loads (motors, solenoids, transformers) without the external RC snubber network that conventional triacs require — saves board space and BOM cost in AC switching applications like industrial motor drives, lighting ballasts, and HVAC valve actuators. The full-pack (isolated) TO-220 tab eliminates the need for an insulating washer when bolting to a grounded heatsink. The 800 V off-state rating (Vdrm) and 12 A RMS continuous rating define the operating limits. Gate trigger current is 35 mA max (Igt). Holding current of 40 mA ensures the device latches on once triggered.","metaTitle":"STMicroelectronics T1235T-8FP Snubberless™ Triac","metaDescription":"ST T1235T-8FP Snubberless™ Alternistor triac, 800V off-state, 12A RMS, 35mA Igt, TO-220FPAB.
