SI8631BB-B-IS1

Digital Isolators Overview

The SI8631BB-B-IS1 is a Skyworks Solutions digital isolator featuring three unidirectional channels with two forward and one reverse path. It utilizes capacitive coupling technology to provide an isolation voltage of 2500 Vrms. The device supports data rates up to 150 Mbps with a propagation delay of 8 ns. Operating on a supply voltage range of 2.5 V to 5.5 V, it functions within temperatures from -40°C to +125°C. Packaged in a narrow SOIC-16, it includes shutdown functionality and meets AEC-Q100 automotive qualification standards.

Digital Isolators Feature Summary

• Capacitive coupling isolation for high-speed signal transmission
• Integrated shutdown control for power management
• Automotive-grade reliability with AEC-Q100 certification

Digital Isolators Applications

• Automotive electronic control units
• Industrial motor drive systems
• Power supply gate driver interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'IS1' corresponds to the narrow SOIC-16 package variant rather than wide or reel options. Confirm that the AEC-Q100 qualification status aligns with automotive application requirements. Ensure the ordering part number matches the exact channel configuration and polarity specifications required by the design schematic.

Digital Isolators Selection Notes

Select this component when high-speed bidirectional communication is not required, as it offers only unidirectional channels. Consider the narrow SOIC-16 footprint constraints against available board space. Evaluate the 150 Mbps data rate capability against system timing requirements to ensure adequate noise immunity and signal integrity at operating frequencies.

Digital Isolators Part Context

This part belongs to the SI863x series of digital isolators from Skyworks Solutions. It provides robust galvanic isolation between circuits while maintaining high data throughput. The series is designed for applications requiring reliable signal transmission across isolated boundaries in noisy environments.

Digital Isolators Replacement Considerations

SI8631AB-B-IS1 offers similar isolation but operates at lower speeds. SI8631BB-B-IS1R provides identical electrical characteristics in a tape-and-reel packaging format for automated assembly.
