Packaged in a through-hole TO-220-3, it is designed for AC load switching in applications like solid-state relays, motor speed controllers, lighting dimmers, and heater controls. The sensitive gate (10 mA max Igt) allows direct triggering from low-voltage logic or microcontroller GPIO without an additional driver transistor. There is no last-time-buy or obsolescence risk on this line item.","metaTitle":"STMicroelectronics T1210T-8T Triac, 800V 12A, TO-220-3","metaDescription":"T1210T-8T triac: 800V off-state, 12A RMS, 10mA sensitive gate, TO-220-3.

This sensitive-gate rating allows direct drive from logic-level signals."},{"question":"What is the equivalent part for T1210T-8T if not available?","answer":"The closest functional equivalent is the T1210T-8FP, which shares the same 800 V off-state voltage, 12 A RMS current, sensitive-gate trigger, and TO-220 package but in a different lead form (full-pack isolated). Verify thermal and mounting compatibility before substituting."},{"question":"Can T1210T-8T be used for inductive load switching?","answer":"Yes, the sensitive gate and 15 mA holding current are suitable for inductive loads such as small motors, solenoids, and transformers. Ensure the load current stays above the holding current at the minimum operating voltage. For highly inductive loads, add a snubber circuit across the triac to limit dV/dt."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/T1210T-8T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/T1210T-8T when reusing this data.
