Non-repetitive surge capability of 140 A at 50 Hz handles the inrush from incandescent lamp filaments, motor start-up, or capacitor bank charging — the device must cool below Tj(max) between surge events. Hold current (Ih) of 5 mA max means the triac latches on once triggered and only commutates off when the load current drops below this threshold near the AC zero-crossing — typical for resistive and lightly inductive loads. ## Package and board integration The TO-220AB insulated tab eliminates the need for a mica washer or insulating pad when mounting to a heatsink — the backside tab is electrically isolated from the die, reducing assembly steps and thermal resistance. Through-hole TO-220-3 footprint suits wave-soldered or hand-soldered boards in power supplies, motor controllers, and solid-state relay replacements where surface-mount alternatives would require additional thermal management. ## Compliance and lifecycle status ROHS3 compliant, covering the full exemption list for lead-free soldering — no additional documentation required for EU market shipments.","metaTitle":"STMicroelectronics T1605G-6I Triac","metaDescription":"ST T1605G-6I logic-level triac, 16 A RMS, 600 V off-state, 5 mA Igt.

The higher voltage margin suits 480 VAC lines, but the full-pack package has different thermal and mounting characteristics — verify fit before substituting."},{"question":"Does T1605G-6I require a heatsink?","answer":"The TO-220AB insulated tab is designed for heatsink mounting. At 16 A RMS continuous, the device dissipates several watts of conduction loss (Vt × It) and requires a heatsink sized for the ambient temperature and airflow. The insulated tab simplifies mounting but does not eliminate the need for thermal management."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/T1605G-6I","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/T1605G-6I when reusing this data.
