Its headline rating is 5000Vrms of galvanic isolation — that is the working isolation voltage the optocoupler holds between the input LED and the output driver stage, sized for motor drives, solar inverters, and industrial power supplies where the control side must be protected from the high-voltage DC bus. The peak output current of 2.5 A with a 2 A source and 2 A sink capability means it can charge and discharge the gate capacitance of a medium-power IGBT or SiC MOSFET fast enough to keep switching losses under control; the 40 ns typical rise and fall times confirm the edge rate is there. The output supply range of 15 V to 30 V covers the standard gate-drive voltages for IGBTs (typically +15 V on, 0 V or -5 V off) and most SiC MOSFETs. ## Common-mode transient immunity — the spec that decides if it works in a noisy inverter A minimum common-mode transient immunity (CMTI) of 50 kV/µs is the figure that separates a gate-drive optocoupler that holds its output state through a fast-switching inverter node from one that glitches. In a half-bridge, when the low-side switch turns off and the high-side switch turns on, the floating output reference of the high-side driver slews at tens of kV/µs. If the optocoupler's CMTI is too low, the output can momentarily change state, causing a shoot-through event. The 50 kV/µs rating here is typical for a 5 kV-rated gate-drive optocoupler and is adequate for most IGBT switching frequencies up to about 20 kHz; for SiC designs switching at 50 kHz or higher, you would want to verify the actual dV/dt at the switching node against this minimum. For dual-sourcing consideration, the closest functional peer is the PS9531L1-AX, a through-hole variant in a tube package with the same 2.5 A peak output, 5 kVrms isolation, and 50 kV/µs CMTI; the key difference is the mounting type — the PS9031-Y-F3-AX is surface-mount, while the PS9531L1-AX is through-hole. That makes the PS9531L1-AX a board-level alternative only if your layout can accommodate a through-hole part.","metaTitle":"PS9031-Y-F3-AX Gate Drive Optocoupler, 5 kVrms, 2.5 A Peak","metaDescription":"Renesas PS9031-Y-F3-AX optical coupling gate driver with 5000Vrms isolation, 2.5A peak output, -40°C to 125°C.
