6N137S(TA)-V

Overview

The Everlight 6N137S(TA)-V is a high-speed logic output optocoupler featuring an open collector configuration. It supports data rates up to 10 Mb/s with rise and fall times of 75 ns. The device provides electrical isolation of 2500 Vrms or 5000 Vrms depending on the specific datasheet reference, with a common mode transient immunity of 5 kV/µs. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.4 V, reverse voltage of 5 V, and maximum output current of 50 mA. Power dissipation is rated at 100 mW. It operates within a temperature range of -40°C to +85°C and is housed in an SMD-8 package.

Feature Summary

• High-speed signal transmission capability supporting 10 Mbps data rates
• Open collector output interface for flexible logic interfacing
• High common mode transient immunity of 5 kV/µs for noise rejection
• Compact surface-mount packaging for automated assembly

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to ensure compatibility with required isolation voltage ratings and packaging specifications. Confirm that the SMD-8 footprint matches the target PCB design constraints. Cross-reference the part number with authorized distributors to validate authenticity and check for any recent manufacturing updates or obsolescence notices prior to finalizing procurement orders.

Selection Notes

Select this component when high-speed isolation is required alongside an open collector output topology. Ensure the system voltage levels are compatible with the 10 mA forward current requirement and that the load can sink the 50 mA maximum output current. Consider the thermal management requirements given the 100 mW power dissipation limit in the compact SMD-8 package during continuous operation.
