SI8631BD-B-ISR

Digital Isolators Overview

The SI8631BD-B-ISR is a Skyworks Solutions digital isolator featuring three channels with two forward and one reverse configuration. It utilizes capacitive coupling technology to provide 5000 Vrms isolation voltage. The device supports data rates up to 150 Mbps with a typical propagation delay of 8 ns. It operates on a supply voltage range of 2.5 V to 5.5 V and is housed in a 16-SOIC package.

Digital Isolators Feature Summary

• Capacitive coupling isolation architecture
• High-speed operation up to 150 Mbps
• Unidirectional channel configuration

Digital Isolators Applications

• General purpose digital isolation
• Automotive systems requiring AEC-Q100 qualification
• Industrial communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix B-ISR indicates reel packaging when ordering. Confirm the SOIC-Wide-16 package dimensions match your PCB footprint requirements. Ensure the 5000 Vrms isolation rating meets your system safety standards. Check for RoHS compliance status before finalizing procurement.

Digital Isolators Selection Notes

Select this component for applications requiring high common-mode transient immunity of 35 kV/µs. The unidirectional nature suits simple signal transmission needs. Consider the 150 Mbps speed limit against your data throughput requirements. The wide operating temperature range supports harsh environments.

Digital Isolators Part Context

This part belongs to the SI863x series of digital isolators from Skyworks Solutions. It shares architectural similarities with other members like the SI8631BT-IS2 but offers higher speed capabilities. The series is designed for robust noise immunity in electrically noisy environments.

Digital Isolators Replacement Considerations

SI8631BD-B-IS is a tube-packaged equivalent within the same family.
