It transmits a switching signal across a reinforced isolation barrier. The 5000Vrms isolation rating covers safety spacing in motor drives, UPS, and solar inverters. The part carries CSA, SEMKO, UL, and VDE approvals. ## 2.5 A peak output and 2 A source-sink — sizing the gate drive for medium-power switches With a peak output rating of 2.5 A and a continuous source/sink capability of 2 A, this driver sits in the mid-range tier of isolated gate drivers. The 40 ns typical rise and fall times keep switching losses manageable. The 175 ns maximum propagation delay and 75 ns maximum pulse width distortion matter when the dead-time budget is tight. ## 50 kV/µs common-mode transient immunity — surviving the switching node A minimum common-mode transient immunity of 50 kV/µs tells you the output side can tolerate fast voltage slewing at the switching node without corrupting the gate signal. In a hard-switched IGBT inverter, the collector voltage can rise at tens of kV/µs during turn-off. The 50 kV/µs rating here is adequate for most IGBT-based designs. ## Supply range and forward diode — biasing the input and output sides The output-side supply range is 15 V to 30 V, which covers the standard gate-drive voltages for IGBTs and MOSFETs. The input side is an LED with a typical forward voltage of 1.56 V and a maximum forward current of 25 mA. ## Package and temperature grade — board-level fit The PS9531L3-V--AX comes in an 8-SMD gull-wing package with a 8-SMD supplier device package designation. It is a surface-mount part intended for reflow assembly. The ROHS3 compliance is current. Cut Tape quantities are also available for prototyping or low-volume builds. The PS9531L3-V--AX carries an active lifecycle status.","metaTitle":"PS9531L3-V-E3-AX Optocoupler Gate Driver, 5000Vrms","metaDescription":"Renesas PS9531L3-V-E3-AX optical coupling gate driver IC. 5000Vrms isolation, 2.5A peak output, 50kV/µs CMTI.

Submit an RFQ for a firm price and lead-time estimate."},{"question":"What is the equivalent or replacement for PS9531L3-V--AX?","answer":"The closest functional sibling is the PS9531L1-AX, which shares the same optical coupling technology, 5000Vrms isolation, 2.5 A peak output, 40 ns rise/fall times, 175 ns propagation delay, and 50 kV/µs CMTI. The key difference is that the PS9531L1-AX is a through-hole (DIP) package in tube format, while the PS9531L3-V--AX is surface-mount (8-SMD gull wing) in Tape & Reel. Choose the PS9531L3 for SMD assembly; choose the PS9531L1 for through-hole boards."},{"question":"Does PS9531L3 require external bootstrap?","answer":"No. The PS9531L3 is an optical coupling gate driver with a dedicated output-side supply pin (15 V to 30 V range,). It does not use a bootstrap architecture — the output stage is powered directly from the VCC supply on the isolated side. This simplifies the design for high-side drive in half-bridge configurations, as long as an isolated DC-DC supply is provided for the high-side channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/PS9531L3-V-E3-AX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/PS9531L3-V-E3-AX when reusing this data.
