SI8652BC-AS1R

Digital Isolators Overview

The SI8652BC-AS1R is an automotive-grade digital isolator from the Si865x series, manufactured by Skyworks Solutions. It features a unidirectional configuration with five channels: three forward and two reverse. The device utilizes capacitive coupling technology to provide electrical isolation rated at 3750 Vrms. It supports data transmission rates up to 150 Mb/s with a propagation delay of 8 ns. Operating on a supply voltage between 2.5 V and 5.5 V, it draws a typical operating current of 5.6 mA. The component is housed in a 16-pin SOIC package and is designed for operation within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• High common-mode transient immunity capability
• Ultra-low power consumption design
• Capacitive coupling isolation architecture

Digital Isolators Applications

• Automotive gate driver circuits
• Inverter control systems
• Motor drive interfaces
• On-board charging (OBC) systems

Digital Isolators Procurement Notes

Verify the specific suffix AS1R indicates reel packaging when sourcing. Confirm that the BC variant meets the required automotive reliability standards for your application. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for moisture sensitivity level requirements prior to assembly processing.

Digital Isolators Selection Notes

Select this component for applications requiring high channel count in a compact form factor. The unidirectional nature suits signal transmission where feedback is not needed across the isolation barrier. Consider the low power profile for battery-sensitive automotive environments. Verify thermal performance within the specified operating temperature range.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators, which are designed for robust performance in noisy environments. The family offers various channel configurations and isolation voltages. The SI8652BC-AS1R specifically targets automotive markets with its qualified reliability and low power characteristics.

Digital Isolators Replacement Considerations

SI8652BC-B-IS1 is a tube-packaged equivalent with similar electrical specifications. SI8652ED-AS offers higher isolation voltage but different power characteristics. Verify pinout and parameter alignment before substitution.
