Its 5000Vrms isolation rating handles the primary-to-secondary safety barrier, and the 2.5A peak output current charges the gate capacitance fast enough to keep switching losses under control. The 50kV/µs common-mode transient immunity means it won't latch or glitch when the high-side rail bounces — a common failure point in noisy inverter environments. ## 40ns rise/fall and 175ns propagation delay — timing budget for the gate drive Rise and fall times are both 40ns typical, matched closely enough that the pulse-width distortion stays under 75ns. The maximum propagation delay (175ns low-to-high and high-to-low) is symmetrical, which simplifies dead-time calculation in half-bridge designs. For switching frequencies up to a few tens of kilohertz, these numbers leave comfortable margin; at higher frequencies you'll want to check the total delay against your switching period. ## Supply range and input drive — what the LED side needs The output-side supply runs from 15V to 30V, covering the typical gate-drive rails for IGBTs (usually +15V on and -5V to -10V off, though this part drives a single positive rail). The input LED forward voltage is 1.56V typical, and the maximum continuous forward current is 25 mA — standard logic-level drive from a 3.3V or 5V microcontroller output through a current-limiting resistor. No separate 5V logic supply is needed; the LED current sets the threshold. ## Temperature range and approvals — industrial and safety-certified Safety approvals from CSA, SEMKO, UL, and VDE cover the reinforced-insulation requirements for mains-connected equipment. The 8-DIP through-hole package is straightforward to hand-replace on a repair bench — a hot-air station or soldering iron works, no reflow profile needed.","metaTitle":"PS9531-V-AX Gate Driver Optocoupler, 5000Vrms, 2.5A Peak","metaDescription":"PS9531-V-AX optocoupler gate driver: 5000Vrms isolation, 2.5A peak output, 50kV/µs CMTI, -40°C to 125°C, 8-DIP.

The PS9531-V-AX specifies a 50kV/µs CMTI versus the HCPL-3120's 15kV/µs typical, giving it an edge in high-noise environments.

The 2.5A peak output current and 40ns rise/fall times are sufficient to drive the gate capacitance of most medium-power IGBT modules (up to about 100A rating) at switching frequencies up to 20-30 kHz. The 5000Vrms isolation covers the safety barrier between the control logic and the high-voltage power stage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/PS9531-V-AX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/PS9531-V-AX when reusing this data.
