1.5 A peak output, 5000 Vrms isolation — gate-drive optocoupler in 8-DIP
The onsemi FOD3150TV is a single-channel optically coupled gate driver delivering 1.5 A peak output current with 5000 Vrms isolation in an 8-DIP through-hole package. It is designed to directly drive IGBTs and power MOSFETs in motor drives, inverters, and industrial power supplies where galvanic isolation and high transient immunity are required. Rise and fall times are 60 ns typical, and propagation delay is 500 ns max, keeping switching losses predictable in hard-switched topologies.
20 kV/µs CMTI — noise immunity in switching environments
Common-mode transient immunity is rated at 20 kV/µs minimum, which means the output remains stable when high dv/dt transients couple across the isolation barrier — a critical parameter in bridge-leg and motor-drive applications where the switching node swings hundreds of volts in nanoseconds. Pulse width distortion is limited to 300 ns max, so the on-time accuracy is preserved even at moderate switching frequencies.
Active production — through-hole 8-DIP availability
the 8-DIP (0.400", 10.16 mm) through-hole package is suitable for wave-solder assembly and manual rework without special handling.
