Product details

The Renesas PS9531L1-AX is a single-channel optical coupling gate driver in an 8-DIP through-hole package. It delivers 2.5A peak output current with 2A source and sink capability, making it a fit for driving medium-power IGBTs and SiC MOSFETs in motor drives, industrial inverters, and switch-mode power supplies. The 5000Vrms isolation rating and 50kV/µs common-mode transient immunity keep the low-voltage control side clean during fast switching edges on the power side.

Output drive and supply range

The 2A source / 2A sink rating (2.5A peak) charges the gate capacitance of a standard 600V / 20A IGBT in roughly the 40ns rise/fall time window. The output supply range of 15V to 30V covers the typical +15V gate drive for IGBTs and the +18V to +20V used for SiC MOSFETs.

Frequently asked questions

What are the alternatives to PS9531L1-AX?

This part sits in the 2.5A peak / 5000Vrms optical gate-driver class. Pin-compatible alternatives from other manufacturers exist but each differs in CMTI, propagation delay, or supply range — confirm timing and isolation margins against your specific gate-drive requirements before swapping.

What is PS9531L1-AX's listed technology?

The PS9531L1-AX uses Optical Coupling technology — an LED optically coupled to a photodetector output stage for galvanic isolation.
