Digital Isolators Procurement Notes

Verify the specific suffix AS2R indicates reel packaging configuration when sourcing components. Confirm that the AEC-Q100 qualification status aligns with automotive application requirements. Ensure the SOIC-WB package dimensions match the target PCB footprint constraints. Check for any recent product change notifications regarding manufacturing updates or material composition changes before finalizing procurement plans.

Digital Isolators Selection Notes

Select this component when four isolated channels are required alongside low-power operation capabilities. The 6000 Vrms rating makes it suitable for applications exceeding standard isolation levels. Consider the 150 Mbps data rate for high-speed interface needs. The sleep mode feature is advantageous for systems requiring extended battery life or thermal management in enclosed spaces.

Digital Isolators Part Context

This part belongs to the Si86Sx series of automotive digital isolators from Skyworks Solutions. It complements other variants like the SI86SL42BE by offering specific power-saving features.
