6N137W

Overview

The onsemi 6N137W is a high-speed logic output optoisolator featuring an open-collector configuration. It supports data rates up to 10Mbps with typical propagation delays of 75ns and rise/fall times of 50ns/12ns. The device provides 2500Vrms isolation voltage and a common-mode transient immunity of 10kV/µs. Operating within a supply voltage range of 4.5V to 5.5V, it handles a maximum DC forward current of 50mA and delivers an output current of 50mA per channel. Packaged in an 8-MDIP format, it functions reliably across temperatures from -40°C to 85°C.

Feature Summary

• High-speed operation supporting 10Mbps data transmission rates
• Robust isolation performance with 2500Vrms voltage rating
• Open-collector logic output for flexible interfacing
• High common-mode transient immunity of 10kV/µs

Applications

• High-speed digital communication interfaces
• Microprocessor system isolation
• Solid-state relay driver circuits
• Noise-immune signal transmission

Procurement Notes

Verify the specific suffix 'W' corresponds to the 8-MDIP package variant when sourcing replacements. Confirm that the component status is discontinued as indicated by recent records. Ensure compatibility with existing 4.5V-5.5V supply rails and check that the open-collector output requirements match the target circuit design before procurement.

Selection Notes

Select this component when high-speed isolation exceeding standard optocoupler limits is required. The open-collector output necessitates an external pull-up resistor for proper logic level generation. Consider the 75ns propagation delay for timing-critical applications. Verify that the 2500Vrms isolation meets the safety requirements of the specific application environment.

Part Context

The 6N137W belongs to the 6N137 series of high-speed optoisolators manufactured by onsemi. This series is designed for applications requiring fast signal transfer between isolated circuits. The W suffix specifically denotes the through-hole 8-MDIP package version, distinguishing it from surface-mount variants like the TSVM or other pin-compatible models within the broader family.

Replacement Considerations

• 6N137TSVM (Surface mount equivalent)
• HCPL-2601 (Pin-compatible alternative)
