Its headline rating is 5000Vrms isolation, backed by CSA, SEMKO, and UL approvals — the safety-agency trifecta that industrial power equipment needs for CE and UL listing. The 2.5A peak output and 2A source/sink current are sized for medium-power IGBT modules in the 600V to 1200V class; the 40ns typical rise and fall times keep switching losses in check without ringing the gate. A 50kV/µs common-mode transient immunity means it holds the gate signal clean even when the high-side dV/dt hits the tens of kilovolts per microsecond — the kind of edge rate you see in silicon-carbide and fast IGBT bridges. ## Output supply range and timing budget The output side runs from 15V to 30V, which covers the standard gate-drive voltage for IGBTs (typically +15V on, -5V to -10V off) and for MOSFETs (10V to 15V). The 175ns max propagation delay (both tPLH and tPHL) sets the lower bound on dead-time in a half-bridge: you need at least that much margin between one channel turning off and the complementary channel turning on, or you get shoot-through. Pulse-width distortion is held to 75ns max, so the on-time of the PWM signal doesn't drift much between the input and the gate — important for accurate duty-cycle control at switching frequencies above 20 kHz. ## Package and mounting It comes in a 6-SDIP Gull Wing — essentially a surface-mount DIP with formed leads that sit flat on the board. The body is 6-SOIC width (6.80mm), so it takes a standard SOIC-6 footprint. Gull-wing leads are hand-solderable and rework-friendly: a hot-air station at 300°C for 20 seconds lifts the part clean without lifting the pad, and the lead pitch is wide enough to inspect the solder joints under a loupe. The input side is a standard LED with 1.56V forward drop and 25 mA max current, so a series resistor from a 3.3V or 5V logic output sets the drive current directly. ## Temperature grade and environment The 125°C ceiling is the junction temperature, not the ambient — in a sealed enclosure with self-heating, you need to derate the output current above 85°C or so. The optical coupling technology inherently provides galvanic isolation, so the input logic side can be referenced to a low-voltage controller ground while the output side rides on the high-side floating supply.","metaTitle":"Renesas PS9331L-E3-AX Optocoupler Gate Driver, 5000Vrms","metaDescription":"Renesas PS9331L-E3-AX optical coupling gate driver: 5000Vrms isolation, 2.5A peak output, 50kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"Optical Coupling","Mounting Type":"Surface Mount","Package / Case":"6-SOIC (0.268\\\", 6.80mm Width)","Approval Agency":"CSA, SEMKO, UL","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Current - Peak Output":"2.5A","Operating Temperature":"-40°C ~ 125°C","Rise / Fall Time (Typ)":"40ns, 40ns","Supplier Device Package":"6-SDIP Gull Wing","Voltage - Output Supply":"15V ~ 30V","Current - Output High, Low":"2A, 2A","Pulse Width Distortion (Max)":"75ns","Voltage - Forward (Vf) (Typ)":"1.56V","Current - DC Forward (If) (Max)":"25 mA","Propagation Delay tpLH / tpHL (Max)":"175ns, 175ns","Common Mode Transient Immunity (Min)":"50kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.04","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.04000","currency":"USD"},{"qty":10,"price":"$3.56300","currency":"USD"},{"qty":100,"price":"$2.91850","currency":"USD"},{"qty":500,"price":"$2.46036","currency":"USD"},{"qty":1000,"price":"$2.25674","currency":"USD"},{"qty":2000,"price":"$2.16342","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d88cfaf6a17473c9e115a76444535c23.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is PS9331L--AX compatible with 5V logic?","answer":"Yes — the input LED has a typical forward voltage of 1.56V and a maximum forward current of 25 mA.
