Its 10 kV/µs minimum static dV/dt ensures the output triac does not false-fire on fast line transients from motor starters or inductive load switching. The 600 V off-state voltage block allows direct switching of 240 VAC or 277 VAC loads without an external snubber in many designs, though the 500 µA hold current sets the minimum load current to keep the triac latched. ## Certified barrier for mains-referenced designs The isolation barrier carries cUL, FIMKO, UL, and VDE approvals — a four-agency certification set that covers North American and European safety standards. This eliminates the need for separate safety-agency review of the optoisolator in the final product. The 1.28 V typical forward voltage and 1.3 mA maximum LED trigger current mean the LED can be driven directly from a 3.3 V or 5 V logic output through a series resistor, keeping the BOM count low. ## Active lifecycle, sourced per RFQ Parts are sourced to order against the BOM quantity — confirm current lead time and price at quote. The surface-mount package suits automated assembly; the Gull Wing leads provide visual solder-joint inspection access.","metaTitle":"FOD4216SV onsemi Triac Optoisolator – 5000 Vrms","metaDescription":"onsemi FOD4216SV triac-output optoisolator: 5000 Vrms isolation, 10 kV/µs min dV/dt, 600 V off-state, -55°C to 100°C.

The part is Active and ROHS3 compliant; we source from our multi-supplier network against your BOM line. Price and lead time are confirmed at quote — no stock-holding claim on this page."},{"question":"Does FOD4216SV require a heatsink for 600 V applications?","answer":"A heatsink is not typically needed for the optoisolator itself — the triac output's power dissipation depends on load current, not off-state voltage. The 600 V off-state rating is a blocking voltage; the device does not dissipate significant power in the off state. For high-load-current designs, evaluate the triac's on-state voltage drop and ambient temperature against the -55°C to 100°C operating range."},{"question":"What is the closest functional second-source to FOD4216SV?","answer":"Within the same onsemi family, the FOD4218SV shares the same 5000 Vrms isolation, 10 kV/µs dV/dt, 60 µs turn-on time, and -55°C to 100°C range. The FOD4208SV and FOD4208SD also match the isolation and dV/dt but differ in trigger current. Verify the LED trigger current (Ift) and off-state voltage against your BOM before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/FOD4216SV","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/FOD4216SV when reusing this data.
