Its 5000Vrms isolation rating and 20kV/µs minimum common-mode transient immunity make it suited for motor-drive, solar-inverter, and industrial power-supply applications where noise on the high-voltage side must not couple back to the controller. ## Switching speed and timing margin Maximum propagation delay is 300ns for both tpHL and tpLH, with a pulse-width distortion ceiling of 250ns. Typical rise and fall times are 15ns and 10ns respectively. These numbers define the minimum dead-time you must budget between high-side and low-side switch transitions in a half-bridge topology — a 300ns delay at 20kHz switching means roughly 0.6% of the period is lost to propagation, which is acceptable for most IGBT gate-drive designs. ## Supply range and drive capability The output side operates from 4.5V to 30V, covering standard gate-drive supply rails for both low-voltage MOSFETs and higher-voltage IGBTs. Output current is rated 2.5mA source and 2.5mA sink — sufficient to drive the gate capacitance of a small IGBT or MOSFET through an external gate resistor, but for larger modules you will want a downstream buffer stage.","metaTitle":"FOD8480 onsemi Optoisolator – 5000Vrms Gate Driver, 6-SOP","metaDescription":"onsemi FOD8480 optocoupler: 5000Vrms isolation, 20kV/µs CMTI, 300ns prop delay, 1-channel gate driver in 6-SOP.

The 2.5mA output current and 300ns propagation delay are within the typical drive requirements for IGBT modules up to about 50A rating, but you should verify gate-charge requirements against the IGBT datasheet.
