This combination directly drives the gate of medium-power IGBTs and SiC MOSFETs without an external buffer stage, simplifying the BOM and saving board area in motor drives, solar inverters, and switched-mode power supplies. The 20 kV/µs minimum common-mode transient immunity ensures the output remains stable during fast dV/dt events at the switching node — a common failure mode in hard-switching topologies where the floating-side ground bounces relative to the logic-side ground. ## 38 ns rise / 24 ns fall edges tighten dead-time budget Typical rise and fall times of 38 ns and 24 ns allow the designer to set a shorter dead-time interval between complementary switches, reducing circulating current losses. Maximum propagation delay is 210 ns for both tpLH and tpHL, with pulse-width distortion capped at 65 ns — this symmetry simplifies timing margin calculations in half-bridge and full-bridge topologies. The output supply range of 10 V to 30 V covers standard gate-drive voltages for IGBTs (typically 15 V) and SiC MOSFETs (18–20 V). The 2.5 A source and 2.5 A sink capability matches the gate charge of common 600 V / 30 A IGBT modules without a push-pull booster. ## Active production, UL recognized, 6-SOP package It carries UL recognition and is ROHS3 compliant. The 6-SOP package — 6.80 mm body width — is a standard footprint shared with other onsemi optocoupled drivers, easing second-sourcing. Sourced per RFQ against your BOM quantity; no stock-holding claim is made here.","metaTitle":"FOD8342V onsemi Optoisolator – 5000 Vrms, 3 A Gate Driver","metaDescription":"onsemi FOD8342V optocoupled gate driver: 5000 Vrms isolation, 3 A peak output, 20 kV/µs CMTI, 6-SOP package.

The 3 A peak output and 10 V to 30 V supply range cover the gate-drive voltage and charge requirements of most SiC MOSFETs in the 600 V to 1200 V class. The 20 kV/µs CMTI is sufficient for the fast switching edges typical of SiC devices."},{"question":"What is the closest functional equivalent to FOD8342V?","answer":"The FOD8343T is a pin-compatible sibling with the same 3 A output but a higher 50 kV/µs CMTI.
