The 35 kV/µs minimum common-mode transient immunity keeps the output state stable during fast switching edges on the high-voltage side — a common failure point in motor-drive and inverter designs where the IGBT collector swings hundreds of volts in tens of nanoseconds. Rise and fall times are 38 ns and 24 ns typical, with a maximum propagation delay of 210 ns and pulse-width distortion held to 65 ns. The output supply range is 10 V to 30 V, covering standard gate-drive rails for IGBTs and power MOSFETs. Forward voltage is 1.43 V typical with a maximum DC forward current of 25 mA. ## What the key ratings mean for your gate-drive design The 3 A peak output is the current available to charge the IGBT or MOSFET gate capacitance during turn-on. For a typical 50 nC gate charge, the rise time into the gate is roughly 17 ns — fast enough for switching frequencies up to 100 kHz in hard-switched topologies. The 2.5 A high/low sourcing and sinking capability is symmetrical, so turn-off is equally fast, reducing dead-time requirements. 5000 Vrms isolation meets reinforced insulation requirements per UL for mains-connected industrial drives and power supplies. The 35 kV/µs minimum CMTI ensures the output does not glitch when the IGBT collector voltage slews rapidly — a spec that matters more than isolation voltage in noisy switching environments. The 8-DIP package is a through-hole footprint — expect a 0.100-inch pitch, 0.300-inch body width, compatible with standard DIP sockets or soldered directly into plated through-holes on a single-sided or double-sided PCB.","metaTitle":"FOD3182 onsemi Optoisolator Gate Driver – 3A Peak, 5000Vrms","metaDescription":"onsemi FOD3182 optocoupled gate driver: 3A peak output, 5000Vrms isolation, 35kV/µs CMTI, 8-DIP through-hole.

Verify the pinout from the respective datasheets before substituting. The FOD3182 offers 3 A peak output compared to the TLP250's typical 1.5 A, so it can drive larger gate charges.
