SI8650BB-AU

Digital Isolators Overview

The SI8650BB-AU is an automotive-grade digital isolator from Skyworks Solutions, featuring five forward channels with unidirectional signal transmission. It utilizes capacitive coupling technology to provide a 2500 Vrms isolation voltage. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns and rise/fall times of 4 ns. Operating within a supply voltage range of 2.5 V to 5.5 V, it draws a typical operating current of 7 mA. It functions reliably across temperatures from -40°C to +125°C and is housed in a QSOP-16 package.

Digital Isolators Procurement Notes

Verify the specific suffix 'AU' corresponds to the QSOP-16 package and standard temperature grade when sourcing. Confirm AEC-Q100 qualification status if required by your automotive application specifications. Ensure compatibility with moisture sensitivity levels during assembly processes. Cross-reference official Skyworks documentation for any updates regarding lead-free compliance or RoHS status prior to final procurement decisions.

Digital Isolators Selection Notes

Select this component for applications requiring five isolated channels with unidirectional data flow. It is suitable where low power consumption and high-speed performance are critical constraints. Consider the 2500 Vrms isolation barrier for safety requirements. Evaluate the QSOP-16 footprint against available PCB space. Compare against other Si865x variants if bidirectional communication or different channel counts are needed.

Digital Isolators Part Context

This part belongs to the Si865x series of digital isolators from Skyworks Solutions. It shares architectural similarities with other members like the SI8650EB-AU but differs in specific packaging or qualification grades.
