Maximum propagation delay is 400 ns with pulse-width distortion capped at 100 ns, giving the designer a predictable timing budget for dead-time insertion. ## Active production — no last-time-buy pressure The FOD3120V carries an Active product status with ROHS3 compliance. Supplied in Tube for the 8-DIP through-hole package. The through-hole form factor suits prototype builds, low-volume production, and rework scenarios where a soldering iron is preferred over a reflow oven. ## Supply range 15 V to 30 V, industrial temperature grade The output supply rail accepts 15 V to 30 V, covering standard gate-drive voltages for IGBTs (15 V on, -5 V to -15 V off) and MOSFETs (10 V to 20 V). Operating temperature from -40°C to 100°C suits industrial enclosures and outdoor telecom cabinets without forced cooling.","metaTitle":"FOD3120V onsemi Optoisolator Gate Driver 3A 5000Vrms 8-DIP","metaDescription":"FOD3120V onsemi optocoupled gate driver, 3A peak output, 5000Vrms isolation, 35kV/µs CMTI, 8-DIP through-hole.

Both use an 8-DIP through-hole package.
