SI86SS41BE-AS2R

Digital Isolators Overview

The SI86SS41BE-AS2R is an automotive-grade digital isolator from Skyworks Solutions, featuring four unidirectional channels with SPI compatibility. It utilizes capacitive coupling technology to provide a 6.0 kVrms isolation voltage rating. The device operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical characteristics include a propagation delay of 9 ns, rise and fall times of 2.5 ns maximum, and a pulse width distortion of 2 ns. It includes a shutdown function and is housed in a 16-pin SOIC-WB package.

Digital Isolators Feature Summary

• Capacitive coupling isolation technology for high electromagnetic immunity
• SPI compatible interface design for automotive applications
• Integrated shutdown control functionality
• Automotive AEC-Q100 qualified reliability

Digital Isolators Applications

• Automotive battery management systems
• Electric vehicle motor control interfaces
• Charging station communication gateways
• Inverter drive signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix AS2R indicates tape and reel packaging configuration against official Skyworks documentation. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the ordering part number matches the exact channel count and voltage rating specifications required by the target application design constraints.

Digital Isolators Selection Notes

Select this component when high isolation voltage and SPI compatibility are required in automotive environments. The unidirectional channel configuration suits applications where signal flow is strictly one-way. Consider the 150 Mb/s data rate limit and 9 ns propagation delay for timing-sensitive designs. Verify thermal performance within the specified -40 C to +125 C operating temperature range.

Digital Isolators Part Context

This part belongs to the Si86SS4x series of automotive digital isolators. It shares the same core isolation architecture as other variants in the family but differs in channel directionality and specific interface compatibility features. The SOIC-WB-16 package provides wide-body pin spacing for enhanced creepage distance compliance in high-voltage automotive PCB layouts.

Digital Isolators Replacement Considerations

SI86SS41BE-AS2 is a tube-packaged equivalent offering identical electrical performance without the reel format change. SI86SM41EE-AS2R serves as a parametric alternative within the broader Skyworks portfolio. Verify pinout compatibility and insulation thickness specifications before substituting any cross-model components.
