SI8663BD-ASR

Digital Isolators Overview

The SI8663BD-ASR is a six-channel unidirectional digital isolator from Skyworks Solutions, designed for automotive applications. It utilizes capacitive coupling technology to provide galvanic isolation with an insulation voltage of 5000 Vrms. The device supports data rates up to 150 Mb/s and features a propagation delay of 8 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and consumes 16.4 mA of working power current. The component is qualified under AEC-Q100 standards and functions reliably across a temperature range of -40°C to +125°C. It is housed in a 16-SOIC package.

Digital Isolators Feature Summary

• Provides high-reliability galvanic isolation via capacitive coupling technology suitable for demanding environments.
• Supports high-speed data transmission with a maximum rate of 150 Mb/s and low propagation delay.
• Complies with automotive qualification standards for robust performance in vehicle systems.

Digital Isolators Applications

• Automotive electronic control units requiring signal isolation
• Industrial communication interfaces needing high voltage isolation
• Power management circuits with ground separation requirements

Digital Isolators Procurement Notes

Verify the specific suffix 'ASR' corresponds to the reel packaging format as indicated by distributor listings. Confirm that the AEC-Q100 qualification status aligns with your project's automotive reliability requirements. Ensure the SOIC-16 package dimensions match your PCB footprint constraints. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Digital Isolators Selection Notes

Choose this component when high channel count isolation is required alongside automotive-grade durability. The 5000 Vrms insulation rating distinguishes it from lower-rated variants like the SI8663BB series. Consider the 150 Mb/s data rate capability for applications exceeding standard speed limits. Verify that the unidirectional channel configuration matches the signal flow direction in your circuit design.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators from Skyworks Solutions. It shares architectural similarities with other members like the SI8663BD-AS but differs in packaging and potentially supply chain distribution channels. The family is characterized by capacitive isolation technology and broad automotive certification.

Digital Isolators Replacement Considerations

SI8663BD-AS serves as a tube-packaged alternative within the same electrical specification set. SI8663BB-B-IU offers similar functionality but with a reduced 2500 Vrms insulation rating. Cross-reference datasheets to confirm pinout compatibility and thermal performance before substitution.
