That 600 V blocking gives comfortable headroom on 240 V AC mains (nominal 340 V peak) and even covers 277 V AC lighting circuits. The 12 A RMS continuous rating suits resistive loads like heaters and incandescent lamps, and derates for inductive loads such as small motors or solenoids — plan the heatsink accordingly. ## Gate drive: 25 mA trigger, 1.3 V gate voltage Gate trigger current is 25 mA max, with a 1.3 V max gate trigger voltage. That is a standard-sensitivity triac — it needs a clean 25 mA pulse from the drive circuit, typically an optocoupler or a small-signal transistor. The 25 mA hold current means the load must draw at least that much to keep the triac latched; below that, the device drops out at the zero-crossing. For low-current loads like a small fan or an LED driver, check that the load current exceeds the hold current. ## Surge capability and thermal environment Non-repetitive surge current is rated 120 A at 50 Hz and 126 A at 60 Hz — enough to handle the inrush of a motor start or a cold-filament lamp bank. The TO-220 Full Pack (TO-220AB insulated) package has the tab fully isolated — no extra insulating washer needed against the heatsink, which simplifies assembly and cuts a BOM line.","metaTitle":"STMicroelectronics BTA12-600CRG Triac, 600 V, 12 A","metaDescription":"Standard triac, 600 V off-state, 12 A RMS, 25 mA gate trigger.

The 'RG' suffix in the order code indicates a RoHS-compliant, halogen-free finish. No separate exemption paperwork is needed for EU or similar markets."},{"question":"What is the difference between BTA12-600CRG and BTA12-600BW?","answer":"Both are 600 V, 12 A standard triacs in the same TO-220 Full Pack package. The key difference is gate sensitivity: the BTA12-600CRG has a 25 mA gate trigger current, while the BTA12-600BW is a logic-level (sensitive-gate) variant with a lower trigger current, typically 5 mA. Choose the CRG for standard optocoupler or transistor drive; pick the BW if your MCU or low-power driver cannot source 25 mA."},{"question":"Can BTA12-600CRG be used for 240 V AC applications?","answer":"Yes. The 600 V off-state rating comfortably exceeds the 340 V peak of a 240 V AC sine wave, with margin for mains transients. It is a standard choice for 240 V AC resistive and inductive loads within the 12 A RMS current limit."},{"question":"What is the gate trigger current for BTA12-600CRG?","answer":"The maximum gate trigger current (Igt) is 25 mA. The maximum gate trigger voltage (Vgt) is 1.3 V. This is a standard-sensitivity triac, not a logic-level device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BTA12-600CRG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BTA12-600CRG when reusing this data.
