Isolation and drive capability for IGBT/MOSFET gates
The Renesas PS9531L2-V-AX is a single-channel optical coupling gate driver in an 8-SMD gull wing package, rated for 5000Vrms isolation. It delivers 2.5A peak output current with 2A source and 2A sink capability, enough to charge and discharge the gate of medium-power IGBTs and MOSFETs in motor drives, industrial inverters, and switch-mode power supplies. The 40ns typical rise and fall times keep switching losses in check, while the 175ns max propagation delay sets the dead-time floor in half-bridge topologies. Common mode transient immunity of 50kV/µs minimum ensures the output stays clean when the high-side switch swings hundreds of volts in a few nanoseconds — a spec that matters more than the headline isolation number in fast-switching designs.
Supply rail and forward current budget
The output supply range is 15V to 30V. The input side needs a forward voltage of 1.56V typical and a maximum forward current of 25 mA. The 75ns maximum pulse width distortion keeps the on/off timing symmetric.
Temperature range and approvals
Approvals include CSA, SEMKO, UL, and VDE, so the part carries the safety marks needed for mains-isolated power stages sold into European and North American equipment. ROHS3 compliance is confirmed, eliminating the need for an exemption review in EU markets.
Surface-mount package and assembly
The 8-SMD gull wing package (supplier device package 8-SMD) is a standard footprint for optocouplers, compatible with reflow soldering. The Tube shipping medium is what you get — no tape-and-reel option is listed, so for automated pick-and-place lines you will need to transfer to a feeder-compatible carrier or order a different packing variant if one exists.
