SI8651BD-AS

Digital Isolators Overview

The SI8651BD-AS is a Skyworks Solutions automotive-grade digital isolator featuring five channels with four unidirectional forward and one reverse path. It utilizes capacitive coupling technology to provide 5000 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 on a supply voltage between 2.375 V and 5.5 V, it draws 18.4 mA. Certified under AEC-Q100, it functions within a temperature range of -40°C to +125°C in a SOIC-16 package.

Digital Isolators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliable operation in vehicle environments.
• High-voltage isolation capability of 5000 Vrms using robust capacitive coupling architecture.
• Integrated shutdown function to minimize power consumption during inactive periods.

Digital Isolators Applications

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm the exact reel packaging quantity and tape specifications. Ensure the component matches the required AEC-Q100 automotive grade certification. Cross-reference the SOIC-16 package dimensions with your PCB footprint requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this model when high-voltage isolation of 5 kV is required for automotive applications. The 5-channel configuration with mixed polarity suits complex signal routing needs. Consider the 150 Mb/s speed limit and 8 ns delay for timing-sensitive designs. Verify thermal performance within the specified -40°C to +125°C operating range.
