SI86SL41BE-AS2R

Digital Isolators Overview

The SI86SL41BE-AS2R is a Skyworks Solutions automotive-grade digital isolator featuring four unidirectional channels. It utilizes capacitive coupling technology to provide high-voltage isolation with a rated insulation voltage of 6.0 kVrms. The device operates within a supply voltage range of 2.375 V to 5.5 V and supports data rates up to 150 Mb/s. It is designed for harsh environments, functioning between -40°C and +125°C, and holds AEC-Q100 qualification. Packaged in SOIC-WB-16 tape and reel format.

Digital Isolators Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• High-voltage capacitive coupling isolation up to 6.0 kVrms
• Low-power architecture optimized for energy efficiency
• Four-channel unidirectional signal transmission

Digital Isolators Applications

• Automotive battery management systems
• Electric vehicle motor control inverters
• On-board charging (OBC) interfaces
• Automotive gate driver isolation

Digital Isolators Procurement Notes

Verify the specific suffix AS2R indicates tape and reel packaging configuration against official Skyworks documentation. Confirm AEC-Q100 qualification status and RoHS compliance details directly from the manufacturer datasheet prior to integration. Ensure the SOIC-WB-16 package dimensions match the target PCB footprint requirements.

Digital Isolators Selection Notes

Select this component when high-voltage isolation exceeding 5 kV is required for automotive applications. The 6.0 kVrms rating provides robust safety margins compared to standard industrial isolators. Choose based on the need for low power consumption in battery-constrained systems and the requirement for four independent unidirectional channels in a single package.

Digital Isolators Part Context

This part belongs to the Si86SL4x series, which focuses on low-power automotive digital isolation. It complements other Skyworks isolators by offering higher voltage ratings than the standard Si864x series while maintaining competitive power profiles suitable for electric vehicle architectures.

Digital Isolators Replacement Considerations

SI86SL41BE-AS2 is the tube-packaged equivalent of the same electrical specification. Cross-reference with SI8641BD-B-IS2R if lower isolation voltage (5 kV) is acceptable.
