It delivers a peak output of 2.5 A and can source or sink 2 A continuously, with 40 ns typical rise and fall times. The 5000 Vrms isolation rating and 50 kV/µs common-mode transient immunity mean it holds up in noisy industrial environments where fast dv/dt events couple across the barrier. ## Isolation and transient immunity — the specs that matter for the barrier With 5000 Vrms isolation, this part meets the reinforced insulation requirements for motor-drive and power-supply designs that need a certified safety barrier. The 50 kV/µs minimum common-mode transient immunity is the figure that keeps the output from false-triggering when the power device switches hard — critical in inverter stages where the floating ground jumps several hundred volts in nanoseconds. If your application sees high dv/dt, this CMTI number is the one to check against your worst-case switching edge. ## Output drive and timing — what the 2.5 A peak buys you The 2.5 A peak output current and 2 A source/sink capability let this driver handle the gate charge of medium-power IGBTs and MOSFETs without an external booster stage. Propagation delay is matched at 175 ns max for both tpLH and tpHL, with pulse-width distortion held to 75 ns max — tight enough to keep dead-time margins predictable in half-bridge topologies. The 40 ns rise/fall times are typical; budget for the max values in your timing analysis if you are running near the switching frequency limit. ## Temperature range and supply — fits the harsh-stuff envelope The output supply range of 15 V to 30 V covers the standard gate-drive rails for IGBTs and most power MOSFETs. The LED forward voltage is 1.56 V typical, with a 25 mA max forward current. ## Package and mounting — surface-mount for automated assembly The 8-SMD gull wing package is a surface-mount footprint that reflows on standard lead-free profiles. The gull-wing leads give good visual inspection access for solder-joint quality — useful if you are qualifying first articles. No exposed pad, so thermal management relies on the copper traces and the ambient airflow; keep the output current within the package's thermal limits if you are running at high duty cycles in a sealed enclosure. It is ROHS3 compliant and holds approvals from CSA, SEMKO, and UL, so it passes the regulatory gate for industrial and commercial equipment sold into Europe and North America.","metaTitle":"PS9531L3-E3-AX Optocoupler Gate Driver, 5000Vrms, 2.5A Peak","metaDescription":"Renesas PS9531L3-E3-AX optical coupling gate driver: 5000Vrms isolation, 2.5A peak output, 50kV/µs CMTI, -40°C to 125°C, 8-SMD gull wing.
