10Mbps open-collector optocoupler with 5000Vrms isolation
The onsemi 6N137SVM is a single-channel optocoupler in the 6N137 family, delivering a 10Mbps data rate across a 5000Vrms isolation barrier. The open collector output with 75ns max propagation delay (tpLH/tpHL) makes it a direct fit for digital signal isolation in PLC digital inputs, motor drive feedback paths, and industrial fieldbus interfaces where the timing budget must accommodate the 30ns rise and 10ns fall times.
Common-mode transient immunity and industrial noise margin
Rated at 10kV/µs (typ) common mode transient immunity, the 6N137SVM rejects fast voltage transients that couple across the isolation barrier in motor drive and inverter environments. The 1.45V typical forward voltage (Vf) at 50mA max forward current (If) keeps the LED drive within standard 5V logic output capability. Input is DC-coupled, so the LED turns on with a steady-state current — no AC coupling or carrier modulation needed.
