SI86S661BB-AU

Digital Isolators Overview

The SI86S661BB-AU is an automotive-grade digital isolator from Skyworks Solutions, featuring six unidirectional channels with a 5/1 input-output configuration. It utilizes capacitive coupling technology to provide 2500Vrms isolation voltage and supports data rates up to 150Mbps. The device operates within a supply voltage range of 2.25V to 5.5V and offers a minimum common-mode transient immunity of 150kV/µs. It is housed in a 16-SSOP package and certified under AEC-Q100 standards for reliable performance in harsh environments.

Digital Isolators Procurement Notes

Verify the specific suffix 'BB' against official Skyworks documentation to confirm pinout and functional mapping, as ordering codes define exact device variants. Ensure compatibility with the required 16-SSOP footprint during PCB layout. Confirm that the selected distributor sources directly from authorized channels to guarantee component authenticity and traceability for automotive quality requirements.

Digital Isolators Selection Notes

Select this component when high-speed bidirectional or unidirectional isolation is required in space-constrained automotive designs. The 5/1 channel split suits applications needing multiple primary-side signals and fewer secondary-side returns. Consider the 150Mbps speed and 150kV/µs CMTI for noisy power electronics environments where standard isolators may fail due to electromagnetic interference.

Digital Isolators Part Context

This part belongs to the Si86S6x series of SPI-compatible digital isolators designed specifically for automotive applications. It complements other Skyworks isolators like the SI8660BB-AU but distinguishes itself through its specific 5/1 channel architecture and optimized performance for high-voltage automotive power stages.

Digital Isolators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include SI86S661EB-AU and SI86S661EB-AUR. Verify package dimensions and electrical characteristics match before substitution.
