SI86SO20EE-AS4R

Digital Isolators Overview

The SI86SO20EE-AS4R is an automotive-grade digital isolator from Skyworks Solutions, featuring a 6.0 kVrms isolation voltage and capacitive coupling technology. It provides two unidirectional channels with inverting outputs, designed for robust signal transmission across isolated boundaries. The component operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 150 Mb/s. It is housed in an SSO-8 surface-mount package and complies with AEC-Q100 standards for automotive reliability.

Digital Isolators Feature Summary

• Capacitive coupling technology ensures high immunity to electromagnetic interference
• Automotive qualification meets AEC-Q100 reliability standards
• Inverting output configuration simplifies logic interface design

Digital Isolators Applications

• Automotive gate driver circuits
• Motor control systems
• On-board charging interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'AS4R' against official Skyworks documentation to confirm reel packaging and automotive grade status. Ensure compatibility with existing PCB footprints and signal polarity requirements before integration. Cross-reference datasheet revisions to account for any recent product change notifications affecting pinout or electrical characteristics.

Digital Isolators Selection Notes

Select this component when high-voltage isolation is required in automotive environments with strict noise immunity needs. The inverting output characteristic must be considered during logic design to ensure correct signal interpretation. Verify that the 6.0 kVrms rating exceeds the system's peak transient voltage requirements for adequate safety margins.

Digital Isolators Part Context

This part belongs to the Si86SOxx series of automotive digital isolators. It complements other Skyworks solutions by offering a compact 8-pin form factor with high isolation capabilities. The series targets applications requiring reliable communication between low-voltage control circuits and high-voltage power stages in electric vehicles.

Digital Isolators Replacement Considerations

Direct substitutes include SI86SO20EC-AS4R for non-inverting variants or SI86SL41EE-AS2 for higher channel counts. Verify pin-to-pin compatibility and electrical parameter alignment with the original specification sheet before substitution.
