It provides 3750 Vrms isolation between input and output sides, with a typical forward voltage of 1.65 V at the LED input. Common-mode transient immunity is rated at 15 kV/µs minimum, which means it rejects fast voltage transients that would otherwise couple across the isolation barrier in motor-drive or inverter applications. The 60 ns max propagation delay (both tpLH and tpHL) keeps the signal timing predictable for synchronous interfaces like SPI or RS-485 isolation. ## Industrial temperature and package fit The 5-SO package (6-SOIC body, 0.173\" width, 4.40 mm) uses a standard SOIC-5 footprint — the same land pattern as many 6-pin SOIC photocouplers, but with one fewer pin on one side. The open-collector output sinks 2 mA per channel, sufficient for driving a 5 V CMOS input or a low-speed optocoupler load. The 20 mA max LED forward current allows direct drive from a 5 V GPIO through a series resistor.","metaTitle":"Renesas PS9151-V-AX Photocoupler, 15Mbps, 3750Vrms, 5-SOIC","metaDescription":"Renesas PS9151-V-AX photocoupler: 15 Mbps data rate, 3750 Vrms isolation, 15 kV/µs CMTI.
