SI8651BB-B-IS1

Digital Isolators Overview

The SI8651BB-B-IS1 is a Skyworks Solutions digital isolator featuring five channels with unidirectional signal paths, comprising 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 typical propagation delay of 8 ns and rise/fall times of 4 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-SOIC narrow body, it includes a shutdown feature.

Digital Isolators Feature Summary

• Provides galvanic isolation via high-reliability capacitive coupling technology for robust signal transmission across isolation barriers.
• Integrates a dedicated shutdown pin to actively disable outputs, reducing power consumption during system idle states or fault conditions.
• Delivers consistent signal integrity with low pulse width distortion and symmetric rise/fall times for precise timing applications.

Digital Isolators Applications

• Industrial automation control systems requiring multi-channel isolation
• Medical equipment signal interfacing and safety monitoring
• Power electronics gate drive circuits for inverters and converters

Digital Isolators Procurement Notes

Verify the specific suffix 'IS1' corresponds to the tube packaging format rather than reel configurations found in other variants like 'ISR'. Confirm that the AEC-Q100 qualification status aligns with automotive application requirements if applicable, as some family members may differ in certification levels. Ensure the SOIC-Narrow-16 footprint matches the target PCB design constraints.

Digital Isolators Selection Notes

Select this component when a five-channel unidirectional isolator with 2.5 kVrms basic isolation is required. Compare against the SI8651BD series if higher 5 kVrms insulation or automotive-specific reliability standards are necessary. Consider the SI8650 series if bidirectional communication or higher voltage ratings are needed for the specific circuit topology.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators from Skyworks Solutions. The family is characterized by high-speed performance and low power consumption using proprietary CMOS SOI technology. The SI8651 variant specifically addresses applications needing multiple isolated channels in a compact surface-mount package.

Digital Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the SI8651BD-B-IS1R for reel-packaged alternatives or the SI8650BC-B-IS1 for different isolation voltage specifications within the same manufacturer portfolio.
