It delivers a peak output current of 2.5A and is rated for 5000Vrms isolation, making it a fit for motor drives, solar inverters, UPS systems, and industrial power supplies where safety isolation between the control and power stages is required. ## Key ratings that decide the fit The 5000Vrms isolation voltage is the primary safety spec — it determines creepage and clearance for reinforced insulation in equipment that must meet UL 508 or IEC 61800-5-1. The 2.5A peak output current and 2A source/sink capability handle the gate charge of medium-power IGBTs (up to about 600V/50A class) without an external booster stage. Propagation delay is 175ns max with a 75ns pulse-width distortion ceiling, which keeps dead-time margins tight in hard-switching bridges. Common-mode transient immunity (CMTI) of 50kV/µs minimum is the spec that separates a gate-driver optocoupler from a general-purpose optocoupler — it prevents the output from glitching when the high-side floating supply jumps during switching transitions. Designs running >20 kHz switching frequencies should verify the CMTI margin against the converter's dV/dt. The output supply range of 15V to 30V covers standard IGBT gate-drive rails (15V on, -5V to -10V off) and most SiC MOSFET drivers. The 1.56V typical forward voltage and 25 mA max forward current are standard for the LED side; the drive-side supply current is not specified here but the 2.5A peak suggests a quiescent draw in the low milliamps. ## Package and approvals Housed in an 8-DIP through-hole package with 0.400-inch (10.16 mm) body width, the PS9531L1-V-AX is a drop-in for standard DIP-8 footprints on single-sided or double-layer PCBs. The through-hole mount is preferred in prototypes, rework, and high-reliability designs where solder-joint fatigue is a concern. The part carries CSA, SEMKO, UL, and VDE safety approvals, which streamlines certification for equipment sold in North America and Europe.
