SI86S640HE-AS2R

Digital Isolators Overview

The SI86S640HE-AS2R is a Skyworks Solutions automotive-grade digital isolator featuring four unidirectional channels. It utilizes capacitive coupling technology to provide an isolation voltage of 6000 Vrms. The device supports data rates up to 150 Mbps and offers a common-mode transient immunity (CMTI) of 150 kV/µs. Packaged in a 16-pin SOIC with a 7.50 mm width, it is designed for high-reliability applications requiring robust signal transmission across isolated boundaries.

Digital Isolators Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards
• High insulation voltage capability of 6000 Vrms
• Capacitive coupling architecture for signal isolation
• High common-mode transient immunity of 150 kV/µs

Digital Isolators Applications

• Automotive powertrain control systems
• Electric vehicle battery management systems
• Motor drive interfaces
• Charging station communication links

Digital Isolators Procurement Notes

Verify the specific suffix AS2R indicates reel packaging when sourcing. Confirm that the component meets AEC-Q100 qualification requirements for your target automotive application. Ensure compatibility with the 16-pin SOIC footprint during PCB layout. Check current availability status as supply constraints may affect lead times.

Digital Isolators Selection Notes

Select this part when high isolation voltage and automotive certification are required. The 150 Mbps speed suits moderate-speed digital interfaces. Consider the 16-pin SOIC package size for board space constraints. Verify input/output voltage levels match the system logic requirements before integration.

Digital Isolators Part Context

This component belongs to the Si86S6x series of automotive digital isolators from Skyworks Solutions. It shares the family's capacitive isolation technology but is distinguished by its 6000 Vrms rating and specific automotive qualification. It complements lower-voltage variants within the same product line.

Digital Isolators Replacement Considerations

SI86S640EE-AS2 is a tube-packaged variant with similar specifications. SI86S640BC-AS1R offers a lower 3.75 kV isolation rating. Direct pin-compatible substitutes require matching CMTI and isolation voltage ratings.
