SI86S640BE-IS2R

Overview

The SI86S640BE-IS2R is a Skyworks Solutions automotive-grade digital isolator featuring four unidirectional channels with capacitive coupling technology. It provides a high insulation voltage of 6000 Vrms and operates within a wide temperature range from -40°C to +125°C. The device utilizes a SOIC-WB-16 surface-mount package and supports data rates up to 150 Mb/s. It is designed for robust signal transmission in electric vehicle powertrains, industrial inverters, and renewable energy systems.

Feature Summary

• Automotive-grade qualification ensuring reliability in harsh environments
• High isolation voltage capability for safe signal transfer across potential barriers
• Capacitive coupling architecture providing long-term stability and immunity to magnetic interference

Applications

• Electric vehicle traction inverter control
• Industrial motor drive systems
• Solar inverter gate driver interfaces

Procurement Notes

Verify the specific suffix IS2R indicates reel packaging when sourcing. Confirm AEC-Q100 qualification status through official Skyworks documentation. Ensure the SOIC-WB-16 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high channel count and strong isolation performance. Compare against other Si86S6x variants based on required insulation voltage and channel directionality. Ensure the operating temperature range meets the specific environmental constraints of the target system design.

Part Context

This part belongs to the Si86S6x family of automotive digital isolators. It complements other members like the SI86S631BE-IS2 by offering four channels instead of three. The series is characterized by its use of advanced capacitive isolation technology for high-reliability applications.

Replacement Considerations

The SI86S640BC-AS1R offers similar functionality but with a lower 3750 Vrms insulation rating. Verify if the reduced isolation voltage meets system safety requirements before substituting.
