SI86SL40BE-AS2R

Digital Isolators Overview

The SI86SL40BE-AS2R is an automotive-grade digital isolator from Skyworks Solutions, featuring four unidirectional channels. It provides a high isolation voltage of 6.0 kVrms and supports data rates up to 150 Mbps. The device utilizes capacitive coupling technology for signal transmission across the isolation barrier. It operates within a supply voltage range of 3.135 V to 5.5 V and functions reliably at temperatures between -40°C and +125°C. Packaged in a 16-pin SOIC-WB (Wide Body) with a 7.50 mm pitch, it meets AEC-Q100 standards for automotive applications.

Digital Isolators Procurement Notes

Verify that the specific suffix AS2R corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets the AEC-Q100 qualification standards mandated by your automotive supply chain requirements. Ensure the wide-body package dimensions align with your PCB layout constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high-voltage isolation is required in space-constrained automotive designs. The wide-body package offers enhanced creepage distances compared to standard packages. Consider the 150 Mbps speed capability for high-frequency signaling needs. Verify that the 6.0 kVrms rating exceeds the system's transient overvoltage requirements.

Digital Isolators Part Context

This part belongs to the Si86SL4x series of low-power digital isolators. It shares architectural similarities with other members like the SI86SL41BE-AS2 but differs in channel configuration and specific electrical characteristics. The series focuses on providing reliable isolation for harsh electromagnetic environments found in modern electric vehicles.

Digital Isolators Replacement Considerations

SI86SL41BE-AS2R is a related variant within the same family. Cross-reference datasheets to ensure pinout compatibility and verify that the alternative part meets the same AEC-Q100 automotive qualification standards before substitution.
