The Snubberless™ construction means the device does not require an external RC snubber network when switching inductive loads like motors, solenoids, or transformers — a direct BOM simplification. Gate trigger current is 35 mA maximum, with a 1.3 V gate trigger threshold, compatible with standard logic-level drive from a microcontroller or optocoupler. The 35 mA holding current ensures the triac stays latched once triggered, even with low load currents near the zero-cross. ## Thermal and surge handling in the IPAK package Non-repetitive surge current is rated 80 A at 50 Hz and 84 A at 60 Hz, giving headroom for inrush from incandescent lamp banks or capacitive input supplies. The surge rating is a single-cycle event; repetitive overcurrents must be kept within the I²t limit of the device.","metaTitle":"ST T835-600H Snubberless Triac, 600V 8A, TO-251","metaDescription":"STMicroelectronics T835-600H Snubberless™ Alternistor triac, 600V off-state, 8A RMS, 35mA Igt, TO-251 IPAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"Snubberless™","Package":"Tube","Triac Type":"Alternistor - Snubberless","Configuration":"Single","Mounting Type":"Through Hole","Package / Case":"TO-251-3 Short Leads, IPak, TO-251AA","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"T835","Voltage - Off State":"600 V","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"TO-251 (IPAK)","Current - Hold (Ih) (Max)":"35 mA","Current - Gate Trigger (Igt) (Max)":"35 mA","Voltage - Gate Trigger (Vgt) (Max)":"1.3 V","Current - On State (It (RMS)) (Max)":"8 A","Current - Non Rep.
