6N137SMT&R

Overview

The 6N137SMT&R is a high-speed logic output optoisolator manufactured by Isocom Components 2004 LTD. It features an open collector output and supports data rates up to 10Mbps. The device provides 5000Vrms isolation voltage with a common-mode transient immunity of 5kV/µs. Packaged in an 8-SMD surface mount DIP configuration, it operates with DC input type. Key electrical specifications include a maximum output current of 50mA per channel and single-channel architecture.

Feature Summary

• High-speed digital signal transmission capability
• Open collector output structure for flexible interfacing
• Robust common-mode transient immunity performance

Applications

• High-speed data communication interfaces
• Digital signal isolation in industrial control systems
• Microcontroller input/output isolation

Procurement Notes

Verify the manufacturer designation as Isocom Components 2004 LTD against official component documentation. Confirm the specific suffix requirements for tape and reel packaging compatibility. Ensure the procurement source provides valid traceability for the 8-SMD package variant. Cross-reference the datasheet version to confirm the 10Mbps speed grade and 5000Vrms isolation rating match project requirements before finalizing orders.

Selection Notes

Select this component when high-speed digital isolation is required over standard optocouplers. The open collector output necessitates an external pull-up resistor for proper logic level translation. Consider the 8-SMD footprint constraints during PCB layout. Verify that the system's common-mode noise environment remains within the specified 5kV/µm immunity limit to ensure reliable operation without false triggering.

Part Context

This part belongs to the family of high-speed logic output optoisolators. It utilizes an LED input coupled to a photodetector driving an open collector transistor stage. The design prioritizes fast switching times and high noise immunity compared to general-purpose transistor output isolators. The surface mount package facilitates automated assembly in compact electronic designs requiring galvanic separation.
