6N137TSR2VM

Overview

The onsemi 6N137TSR2VM is a high-speed logic output optocoupler featuring an open collector output and a single channel. It supports data rates up to 10 Mbps with typical rise and fall times of 30 ns and 10 ns, respectively. The device provides an isolation voltage of 5000 Vrms and a common-mode transient immunity of 10 kV/µs. It operates within a supply voltage range of 4.5 V to 5.5 V and functions at temperatures from -40°C to 100°C. Packaged in an 8-SMD surface-mount configuration, it delivers a maximum output current of 50 mA.

Feature Summary

• High-speed operation enabled by a dedicated photodiode bias connection for improved speed over conventional phototransistor designs
• Robust noise immunity characterized by a minimum common-mode transient rejection capability
• Open collector output architecture suitable for interfacing with various logic families

Applications

• High-speed digital signal isolation in communication interfaces
• Noise-immune signal transmission in industrial control systems
• Isolation barriers in microprocessor-based monitoring circuits

Procurement Notes

Verify the specific suffix 'SR2' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure that the selected variant matches the thermal management requirements for the intended operating temperature range. Cross-reference the manufacturer part number against official datasheets to confirm the exact pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when high-speed data transfer exceeding standard optocoupler capabilities is required. The open collector output necessitates an external pull-up resistor for proper logic level generation. Consider the 5000 Vrms isolation rating for applications requiring significant potential difference between input and output grounds. Evaluate the 10 kV/µs CMTI specification for environments with high electromagnetic interference.

Part Context

This device belongs to the 6N137 series of high-speed optocouplers manufactured by onsemi. It utilizes advanced LED-to-photodiode technology rather than traditional phototransistors to achieve superior switching speeds. The series is designed for applications demanding fast response times and reliable signal integrity across isolated boundaries in compact surface-mount packages.
