SI86S621BC-ASR

Digital Isolators Overview

The SI86S621BC-ASR is an automotive-grade digital isolator from the Si86S6x series, manufactured by Skyworks Solutions. It features two unidirectional channels with capacitive coupling technology and a 3.75 kVrms isolation voltage rating. The device supports data rates up to 150 Mb/s with a propagation delay of 13.5 ns. Operating within a supply voltage range of 2.25 V to 5.5 V, it functions reliably between -40°C and +125°C. Packaged in an SOIC-NB-8 format, this component includes shutdown functionality and meets AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Capacitive coupling isolation providing high noise immunity
• Integrated shutdown control for power management

Digital Isolators Applications

• Automotive gate driver circuits
• Inverter control systems
• On-board charger interfaces

Digital Isolators Procurement Notes

Verify the specific suffix ASR indicates reel packaging configuration. Confirm AEC-Q100 certification status through official Skyworks documentation before integration into safety-critical automotive designs. Ensure input voltage levels match the specified 2.25 V to 5.5 V operational range.

Digital Isolators Selection Notes

Select this component when automotive reliability and bidirectional signal isolation are required. Compare against non-automotive variants if environmental ratings differ. Verify channel count matches system requirements, as other models may offer single or four-channel configurations.

Digital Isolators Part Context

Part of the Si86S6x family designed for robust performance in harsh environments. Distinguished from standard industrial versions by enhanced thermal stability and automotive-specific testing protocols. Shares architectural similarities with SI86S610BC-ASR but provides dual-channel capability.

Digital Isolators Replacement Considerations

SI86S621BC-IS serves as the industrial equivalent without automotive qualification. SI86S620BC-ASR offers identical electrical characteristics but lacks the specific automotive designation.
