SI8661BD-B-IS2R

Digital Isolators Overview

The SI8661BD-B-IS2R is a Skyworks Solutions digital isolator featuring six channels with five forward and one reverse direction. It utilizes capacitive coupling technology to provide an insulation voltage of 5000 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and functions at temperatures from -40 °C to +125 °C. Packaged in a SOIC-Wide-16 reel, it meets AEC-Q100 automotive qualification standards.

Digital Isolators Feature Summary

• Provides high-voltage isolation via capacitive coupling for signal integrity
• Supports bidirectional communication with mixed channel polarity configuration
• Ensures system reliability through automotive-grade qualification compliance

Digital Isolators Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces needing high noise immunity
• Power conversion systems with isolated gate drive requirements

Digital Isolators Procurement Notes

Verify the specific suffix IS2R indicates reel packaging when ordering. Confirm AEC-Q100 qualification status matches project requirements. Check moisture sensitivity levels for proper storage handling. Ensure the SOIC-Wide-16 package dimensions fit the target PCB layout constraints before finalizing procurement decisions.

Digital Isolators Selection Notes

Select this component when high-speed data transmission above 150 Mb/s is not required but robust 5 kV isolation is critical. Consider the mixed unidirectional channel layout for asymmetric signal paths. Evaluate power consumption against other Si866x variants if lower current draw is necessary. Verify thermal performance within the specified operating temperature range for the intended enclosure.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators from Skyworks Solutions. It shares core architectural features with other members like the SI8661BD-B-IS2 but differs in packaging format and specific qualification ratings. The series is designed for applications demanding reliable signal transmission across isolation barriers in noisy environments.

Digital Isolators Replacement Considerations

The SI8661BD-B-IS2 is a tube-packaged equivalent with identical electrical specifications. Verify pin compatibility and package width differences between SOIC-Wide-16 and standard SOIC-16 during substitution planning.
