SI8651EB-B-IU

Digital Isolators Overview

The SI8651EB-B-IU is a Skyworks Solutions digital isolator featuring five channels with four unidirectional forward and one reverse path. It utilizes capacitive coupling technology to provide 2500 Vrms isolation voltage. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns. Operating on a supply voltage range of 2.5 V to 5.5 V, it draws 6.6 mA of working power current. The component operates within a temperature range of -40°C to +125°C and is housed in a QSOP-16 package.

Digital Isolators Feature Summary

• Capacitive coupling isolation architecture for high-speed signal transmission
• Automotive-grade qualification ensuring reliability in demanding environments
• Ultra-low power consumption design for energy-efficient operation

Digital Isolators Applications

• Automotive electronic control units (ECUs)
• Industrial automation systems requiring galvanic isolation
• Power supply circuits with high-voltage separation needs

Digital Isolators Procurement Notes

Verify the specific suffix 'B-IU' corresponds to the QSOP-16 package and automotive grade when sourcing. Confirm that the manufacturer is Skyworks Solutions, Inc., as distributor listings may vary. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the official datasheet before integration into production lines.

Digital Isolators Selection Notes

Select this model for applications requiring five isolated channels with mixed forward and reverse directionality. The 2.5 kV rating suits standard automotive and industrial isolation requirements. Consider the 150 Mb/s speed limit against system timing constraints. The low power profile makes it suitable for battery-operated or thermally constrained designs compared to higher-power alternatives.

Digital Isolators Part Context

This component belongs to the Si865x series of digital isolators from Skyworks Solutions. It complements other variants like the SI8651EC-B-IS1 which offers higher insulation voltage but different packaging. The series is designed to replace traditional optocouplers in modern interface applications, providing better performance and smaller form factors.
