Its 5000Vrms isolation rating provides the reinforced safety barrier required in industrial equipment, while the 20kV/µs common-mode transient immunity keeps the output state stable during fast switching events — a critical parameter in noisy inverter environments where false triggering can cause shoot-through. The output supply range spans 4.5V to 30V, making it compatible with both 5V and 24V gate-drive rails. Propagation delay is 300ns max, which supports switching frequencies up to several tens of kHz with adequate dead-time margin. Rise and fall times are 15ns and 10ns typical, respectively, keeping the gate-drive edges clean. ## Sourcing and lifecycle status The FOD8480T carries an Active lifecycle status and is ROHS3 compliant. ## Temperature grade and environment Rated for -40°C to 100°C operating temperature, the FOD8480T covers industrial and outdoor telecom enclosures. The optical coupling technology inherently provides galvanic isolation between the input LED and the output detector, eliminating ground loops in mixed-voltage systems. Approvals include IEC/EN/DIN and UL, easing certification for end equipment.","metaTitle":"FOD8480T onsemi Optoisolator – 5000Vrms Gate Driver, 6-SOP","metaDescription":"FOD8480T onsemi optocoupler: 5000Vrms isolation, 20kV/µs CMTI, 300ns propagation delay.

It can drive the gate of a small IGBT or MOSFET directly; for larger power devices, a downstream gate-driver buffer is recommended to handle the gate charge."},{"question":"What is the difference between FOD8480T and FOD8343T?","answer":"The FOD8343T is a higher-current gate driver (3 A output) with faster rise/fall times (38ns, 24ns) and higher CMTI (50kV/µs). The FOD8480T has a 2.5mA output and 20kV/µs CMTI — it is suited for lower-power gate-drive stages where the FOD8343T's current capability is not needed."},{"question":"Is FOD8480T compatible with 3.3V logic?","answer":"The input LED forward voltage is 1.4V typical, and the maximum forward current is 20 mA. A 3.3V logic output can drive the LED through a current-limiting resistor; the logic-high voltage must exceed the LED forward voltage plus the resistor drop. The output supply (4.5V to 30V) is independent of the input side."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/FOD8480T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/FOD8480T when reusing this data.
