SI86S641BC-AS1

Digital Isolators Overview

The SI86S641BC-AS1 is a Skyworks automotive-grade digital isolator featuring four unidirectional channels with capacitive coupling technology. It provides an isolation voltage of 3750 Vrms and supports data rates up to 150 Mbps. The device exhibits a common-mode transient immunity of 150 kV/µs and operates within a temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC-NB, it complies with AEC-Q100 standards for automotive reliability.

Digital Isolators Feature Summary

• Four-channel unidirectional signal isolation using capacitive coupling
• Automotive qualification compliant with AEC-Q100 standards
• High common-mode transient immunity of 150 kV/µs

Digital Isolators Applications

• Automotive battery management systems
• Electric vehicle motor control interfaces
• Inverter gate drive isolation

Digital Isolators Procurement Notes

Verify the specific suffix AS1 against the official Skyworks datasheet to confirm package dimensions and tape-and-reel or tube availability. Ensure the component meets the required AEC-Q100 grade for the target automotive application environment.

Digital Isolators Selection Notes

Select this model when four isolated bidirectional paths are not required, as it offers only unidirectional channels. Compare the 3750 Vrms rating against system insulation requirements and ensure the 150 Mbps speed aligns with communication bus timing constraints.

Digital Isolators Part Context

This part belongs to the Si86S6x series of automotive digital isolators. It utilizes Skyworks' proprietary capacitive isolation technology to provide robust signal transmission across isolation barriers while maintaining low power consumption and high reliability in harsh environments.

Digital Isolators Replacement Considerations

SI86S641BB-AU is a parameter-equivalent alternative offering similar functionality but packaged in a 16-SSOP format instead of SOIC-NB. Verify pinout compatibility before substitution.
