6N137SVM

Overview

The onsemi 6N137SVM is a high-speed optocoupler featuring an open collector output and SMD-8 packaging. It supports data rates up to 10 MB/s with a typical common-mode transient immunity of 10 kV/µs. The device provides an isolation voltage of 5000 Vrms, ensuring robust signal transmission across isolated boundaries. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.4 V, and a reverse voltage rating of 5 V. The output stage delivers a maximum collector current of 50 mA with a current transfer ratio of 20%. Transition times are specified at 30 ns for rise and 10 ns for fall, enabling efficient performance in fast digital communication applications.

Procurement Notes

Verify the specific suffix 'SVM' against the official datasheet to confirm the surface mount package type and RoHS compliance status. Ensure that the procurement channel provides valid manufacturer documentation matching the part number. Cross-reference the isolation voltage rating and output configuration with system requirements before finalizing orders. Confirm that the supplier offers genuine components with traceable origin to avoid counterfeit risks.

Selection Notes

Select this component when high-speed signal isolation is required with open collector output flexibility. The 10 MB/s data rate suits applications needing rapid switching without significant propagation delay. Consider the 5000 Vrms isolation barrier for safety-critical designs. Evaluate the 50 mA output current capability against load requirements. Ensure the SMD-8 footprint aligns with PCB layout constraints and thermal management needs.
