SI8651BB-B-IS1R

Digital Isolators Overview

The SI8651BB-B-IS1R is a Skyworks Si865x series digital isolator featuring five channels with unidirectional signal paths, configured as four forward and one reverse channel. It utilizes capacitive coupling technology to provide an insulation voltage of 2500 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns and includes a shutdown function. Operating within a supply voltage range of 2.375 V to 5.5 V, it is housed in a 16-SOIC narrow package and meets AEC-Q100 automotive qualification standards.

Digital Isolators Feature Summary

• Capacitive coupling isolation technology for high reliability
• Integrated shutdown control for power management
• Automotive-grade qualification under AEC-Q100 standards

Digital Isolators Applications

• Automotive electronic control units
• Industrial motor drive systems
• Power supply feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix 'B' indicates the correct package variant and 'IS1R' confirms the reel packaging format. Confirm that the AEC-Q100 qualification status aligns with your application requirements. Ensure the 2500 Vrms isolation rating meets system safety standards. Check for RoHS compliance details if required by your manufacturing process. Validate the 16-SOIC narrow footprint against your PCB layout constraints.

Digital Isolators Selection Notes

Select this component when unidirectional signal transmission is required across isolated boundaries. The five-channel configuration suits applications needing multiple independent signal paths. The 150 Mb/s data rate supports standard communication protocols. Consider the 8 ns propagation delay for timing-sensitive designs. The wide operating temperature range ensures functionality in harsh environments.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators from Skyworks Solutions. The family offers various channel counts and isolation voltages. The SI8651 variant specifically provides five channels. The B suffix denotes the specific package and pinout configuration. The IS1R suffix indicates the tape and reel shipping method.

Digital Isolators Replacement Considerations

SI8651BB-B-IS1 is the tube-packaged equivalent of this reel-part. SI8451BB-B-IS1R is a related part with different propagation delay characteristics. Verify pin compatibility and isolation voltage ratings before substitution.
