6N137A

Overview

The Vishay 6N137A is a high-speed logic output optocoupler featuring an open-collector phototransistor. It provides robust isolation with a dielectric strength of 5000Vrms and common mode transient immunity of 1kV/µs. The device supports data rates up to 10 MBd, operates on supply voltages from 4.5V to 7V, and functions within a temperature range of -40°C to +85°C.

Feature Summary

• High-speed signal transmission capability for digital applications
• Robust electrical isolation with high dielectric strength
• Open-collector output configuration for flexible interfacing

Applications

• Industrial communication systems requiring noise immunity
• Microprocessor system isolation
• Signal transmission in high-noise environments

Procurement Notes

Verify the specific suffix (e.g., X001, X007T) against your board design requirements, as packaging and lead finish vary by variant. Confirm RoHS compliance status, as some listings indicate non-compliance. Ensure the supplier source matches the manufacturer's authorized distribution channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The open-collector output necessitates an external pull-up resistor. Verify that the input current limits and voltage requirements align with the driving circuitry before finalizing the design.

Part Context

This part belongs to the 6N137 series of high-speed optocouplers originally developed by HP and later produced by Broadcom and Vishay. The series is widely recognized for its speed and reliability in isolating digital signals across different voltage domains in electronic circuits.

Replacement Considerations

Direct substitutes include the 6N137 and 6N137#060. Verify pinout compatibility and electrical specifications such as CMTI and propagation delay when cross-referencing with other manufacturers' equivalents.
