Its 10 mA maximum gate trigger current (Igt) means it switches directly from a microcontroller I/O pin, an optocoupler output, or a low-power logic gate — no driver transistor needed between the control signal and the gate. ## 600 V off-state and surge capability Rated for 600 V off-state blocking, this triac comfortably handles 230 VAC and 277 VAC mains with margin for normal line transients. The non-repetitive surge current rating of 80 A at 50 Hz and 84 A at 60 Hz (Itsm) tells you it can survive the inrush from a motor start, a lamp cold filament, or a capacitive load without failing short. ## Temperature range and package fit The TO-220-3 package has a metal tab for heatsinking — bolt it to a chassis or a dedicated heatsink when the RMS current exceeds about 4 A in free air, or derate per the datasheet curve. ## Active lifecycle and compliance Listed as Active by STMicroelectronics — no end-of-life or last-time-buy risk for ongoing production or new designs. Fully ROHS3 compliant, so no exemption paperwork needed for EU, UKCA, or global markets.","metaTitle":"STMicroelectronics BTB08-600SWRG Triac, 8 A, 600 V, TO-220","metaDescription":"ST BTB08-600SWRG sensitive-gate triac: 8 A RMS, 600 V off-state, 10 mA Igt.

The only difference is the off-state voltage: 600 V for this part versus 800 V for the TWRG variant. If your board's peak line voltage never exceeds 600 V (e.g., 230/277 VAC mains), the 600SWRG is a direct drop-in replacement without any PCB or heatsink change."},{"question":"What is the closest lower-current sibling in the same family?","answer":"The BTB06-600SWRG is the 6 A RMS version, same 600 V off-state, same sensitive-gate logic-level trigger, same TO-220-3 package. It is a drop-in for BOM positions where the load current stays under 6 A RMS and you want a lower-cost or lower-dissipation part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BTB08-600SWRG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BTB08-600SWRG when reusing this data.
