It belongs to the Snubberless™ series, meaning it is designed for inductive-load switching without the usual RC snubber network across the main terminals — the device's own turn-off dV/dt capability handles the commutation. Typical applications include AC motor speed controls, industrial heating, lighting dimmers, and solid-state relays where the load is resistive or moderately inductive and the line voltage is 230 VAC or 400 VAC nominal. Sourcing is limited to the surplus and broker channel. The 800 V off-state voltage gives headroom for 400 VAC line applications — the peak of a 400 VAC sine wave is about 565 V, so the 800 V rating leaves margin for mains transients without avalanche. The 8 A RMS on-state current is the continuous load rating; for motor or heater loads with inrush, the non-repetitive surge capability of 80 A at 50 Hz and 84 A at 60 Hz covers the cold-start spike. Gate trigger current is 30 mA max with a 1.3 V max gate trigger voltage — standard logic-level drive from a microcontroller or optocoupler will fire it, but the 50 mA holding current means the load must draw at least that much to stay latched; a very light load may drop out at the zero-cross.","metaTitle":"STMicroelectronics T830-8FP Snubberless Triac, 800 V, 8 A","metaDescription":"STMicroelectronics T830-8FP Snubberless alternistor triac, 800 V off-state, 8 A RMS, TO-220FPAB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"Snubberless™","Package":"Tube","Triac Type":"Alternistor - Snubberless","Configuration":"Single","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"T830","Voltage - Off State":"800 V","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"TO-220FPAB","Current - Hold (Ih) (Max)":"50 mA","Current - Gate Trigger (Igt) (Max)":"30 mA","Voltage - Gate Trigger (Vgt) (Max)":"1.3 V","Current - On State (It (RMS)) (Max)":"8 A","Current - Non Rep.
