It is designed for AC load switching where a low-power logic signal — from a microcontroller, timer, or optocoupler — directly triggers the gate. Typical applications include small motor drives, lighting dimmers, solid-state relays, and valve actuators in industrial and commercial equipment. That simplifies the BOM and saves board space in compact designs like appliance control boards or HVAC zone valves. ## 600 V off-state and 4 A on-state — sizing the load The 600 V off-state voltage gives comfortable margin for 240 V AC mains switching (peak ~340 V), and the 4 A RMS on-state current covers loads up to about 900 W resistive at 240 V. The non-repetitive surge rating of 30 A at 50 Hz and 31 A at 60 Hz handles inrush from incandescent lamps or small motor start-up without immediate failure. ## Package and mounting — field-replaceable without a reflow oven The DPAK (TO-252) surface-mount package can be soldered with a temperature-controlled iron or a hot-air station, making it practical for field repairs where a reflow oven is not available. The tab is the main thermal path and also carries the MT2 terminal — ensure the PCB footprint has adequate copper area and a via stitch to the inner layers for heat spreading.","metaTitle":"STMicroelectronics T410-600B Triac","metaDescription":"STMicroelectronics T410-600B sensitive-gate triac, 600V off-state, 4A RMS on-state, DPAK surface mount.

For a surface-mount alternate with higher current, consider the T1235-600G (12 A, Snubberless type) — verify the gate drive and snubber requirements for your application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/T410-600B","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/T410-600B when reusing this data.
