That saves board space, reduces BOM count, and eliminates the snubber's power dissipation. The TO-220-3 package is through-hole, with a metal tab for heatsink mounting. The tab is electrically connected to the MT2 terminal — account for that in layout if using a shared heatsink. The single triac configuration means one device per package; no internal paralleling. The supplier device package is TO-220, which is the standard 3-lead isolated or non-isolated variant; verify the specific mounting-hole and tab dimensions against your heatsink design. No NRND or EOL notice is on record. For dual-source resilience, the closest functional peer within the same Snubberless Alternistor family is the T1235-600G, which shares the 600 V / 12 A rating and Snubberless Alternistor type, though it comes in a surface-mount package (not through-hole).","metaTitle":"STMicroelectronics BTA12-600BWRG Triac","metaDescription":"BTA12-600BWRG Snubberless™ triac from ST. 600 V off-state, 12 A RMS on-state, TO-220 package.

That reduces BOM count, saves PCB space, and eliminates snubber resistor heat."},{"question":"What are the alternatives to BTA12-600BWRG?","answer":"Within the same Snubberless Alternistor family, the T1235-600G is a 600 V / 12 A surface-mount part. For a lower-current through-hole option, the BTA06-600SRG is a 6 A logic-level triac but is not Snubberless — it needs a snubber for inductive loads."},{"question":"What is the difference between BTA12-600B and BTA12-600BWRG?","answer":"The suffix 'WRG' indicates the specific packaging and environmental compliance variant — in this case, RoHS3 compliance and a tube package. The 'B' suffix denotes the Snubberless Alternistor type. The core electrical ratings (600 V, 12 A) are the same across the BTA12-600B family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BTA12-600BWRG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BTA12-600BWRG when reusing this data.
