1 Mbps open-collector optocoupler with 2500 Vrms isolation
The Renesas PS9822-1-V-AX is a single-channel DC-input optocoupler from the NEPOC series, providing galvanic isolation rated at 2500 Vrms. The part operates from a 7 V supply and can sink up to 20 mA per channel.
Common-mode transient immunity — 15 kV/µs minimum
With a minimum common-mode transient immunity (CMTI) of 15 kV/µs, this optocoupler is designed to reject fast dV/dt transients common in motor-drive, inverter, and industrial power-conversion environments. The open-collector output gives the designer flexibility to pull up to a logic rail or a higher voltage bus, though propagation delay (700 ns tpLH max, 500 ns tpHL max) should be factored into timing budgets for switching applications.
