The Snubberless design means it commutates inductive loads without an external RC snubber — a real BOM simplification for motor, valve, and transformer drives where the classic triac would need the extra network to avoid false triggering on dV/dt. The 35 mA gate trigger current (Igt max) is a standard logic-level threshold, compatible with optocoupler or MCU-driven gate drive circuits. The 80 A / 84 A non-repetitive surge rating (50/60 Hz) handles the cold-start inrush of incandescent lamps or capacitive loads without exceeding the device's SOA. The 150°C Tj ceiling gives thermal headroom for continuous 8 A conduction without forced airflow, provided the D2PAK tab is properly soldered to a copper plane for heat spreading.","metaTitle":"STMicroelectronics T835H-6G Triac, 600 V, 8 A, Snubberless","metaDescription":"ST T835H-6G Alternistor Snubberless triac: 600 V off-state, 8 A RMS, 35 mA Igt, -40°C to 150°C Tj, D2PAK.","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":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"T835","Voltage - Off State":"600 V","Operating Temperature":"-40°C~150°C(TJ)","Supplier Device Package":"D2PAK","Current - Hold (Ih) (Max)":"35 mA","Current - Gate Trigger (Igt) (Max)":"35 mA","Voltage - Gate Trigger (Vgt) (Max)":"1 V","Current - On State (It (RMS)) (Max)":"8 A","Current - Non Rep.

The difference is the package: the -6G variant is the D2PAK (TO-263) surface-mount package, while the -6F variant is typically the TO-220FP fully isolated through-hole package. The choice depends on your mounting and thermal management approach — D2PAK for reflow assembly and PCB heat sinking, TO-220FP for bolt-down to a heatsink."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/T835H-6G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/T835H-6G when reusing this data.
