6N137TSVM

Overview

The onsemi 6N137TSVM is a high-speed logic output optocoupler featuring an open collector output and Schottky-clamped input. It provides a data rate of 10 MB/s with typical propagation delays of 75 ns for both low-to-high and high-to-low transitions. The device offers a common-mode transient immunity of 10 kV/µs and supports an isolation voltage of 5000 Vrms. It operates within a supply voltage range of 4.5 V to 5.5 V, accepts a maximum forward current of 50 mA, and delivers an output current of 50 mA per channel. The component is housed in an 8-SMD package.

Feature Summary

• High-speed operation with 10 MB/s data rate capability
• Schottky-clamped photodiode input for fast switching
• Open collector output configuration
• High common-mode transient immunity

Applications

• High-speed digital signal isolation
• Solid-state relay driver circuits
• Industrial communication interfaces
• Microcontroller peripheral isolation

Procurement Notes

Verify the specific suffix 'S' indicates surface mount packaging distinct from through-hole variants. Confirm RoHS compliance status and lead-free finish specifications against the latest manufacturer documentation. Ensure the operating temperature range meets application requirements. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design specifications.

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 5000 Vrms isolation rating for safety-critical applications. Verify that the 10 kV/µs CMTI rating aligns with the noise environment of the target system to prevent false triggering.

Part Context

This part belongs to the 6N137 series of high-speed optocouplers manufactured by onsemi. It serves as a surface-mount variant of the widely used 6N137 family, offering equivalent electrical performance in a compact SMD form factor. The series is designed for applications requiring rapid signal transmission across isolation barriers while maintaining signal integrity.

Replacement Considerations

Direct pin-compatible replacements include the 6N137TVM (through-hole DIP) for board layout adjustments. Other high-speed logic output optocouplers may require schematic modifications due to differing pinouts or output configurations. Always verify electrical parameters match before substituting.
