SI86S640EB-AUR

Overview

The SI86S640EB-AUR is an automotive-grade digital isolator from Skyworks Solutions, utilizing capacitive coupling technology. It features four unidirectional channels with a data rate of 150 Mbps and a common-mode transient immunity of 150 kV/µs. The device supports a supply voltage range of 2.25 V to 5.5 V and provides 2500 Vrms isolation voltage. Packaged in a 16-lead SSOP (3.90 mm width) reel, it is designed for high-reliability applications requiring robust signal transmission across isolation barriers.

Feature Summary

• Four-channel unidirectional signal isolation
• Automotive-grade reliability certification
• High common-mode transient immunity
• Capacitive coupling technology

Applications

• Automotive powertrain control systems
• Electric vehicle battery management systems
• Motor drive inverters
• Charging station interfaces

Procurement Notes

Verify the specific suffix 'AUR' indicates the tape-and-reel packaging format distinct from tube-packaged variants like 'AU'. Confirm that the 150 kV/µs CMTI rating aligns with your system's noise environment requirements. Ensure the 16-lead SSOP footprint matches your PCB layout constraints before finalizing component selection.

Selection Notes

Select this component when four independent unidirectional channels are required within a single package. The 2500 Vrms isolation level suits standard automotive isolation needs. Consider the 150 Mbps data rate limit for high-speed communication links. The automotive qualification ensures suitability for harsh operating environments compared to industrial-grade alternatives.

Part Context

This part belongs to the Si86S6x series of automotive digital isolators. It complements other variants in the family by offering a specific combination of channel count, directionality, and packaging. The series emphasizes low power consumption and high reliability for critical automotive electronics.

Replacement Considerations

Direct substitutes include SI86S640EB-AU (tube package) or SI86S640BC-AS1R (higher isolation). Verify pinout compatibility and isolation voltage ratings when cross-referencing with other Skyworks isolator models.
