SI86S621EE-AS4R

Digital Isolators Overview

The SI86S621EE-AS4R is a digital isolator from the Si86S6x series, manufactured by Skyworks Solutions. It features two unidirectional channels with capacitive coupling isolation technology. The device provides a high insulation voltage of 6000 Vrms and is designed for automotive applications, meeting AEC-Q100 qualification standards. It is housed in an SSO-8 surface-mount package and operates within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• High-voltage capacitive coupling isolation barrier
• Unidirectional signal transmission capability

Digital Isolators Applications

• Automotive electronic control units
• Inverter gate drive circuits
• Motor control systems

Digital Isolators Procurement Notes

Verify the specific suffix AS4R indicates tube packaging configuration distinct from other variants. Confirm AEC-Q100 automotive qualification status through official Skyworks documentation. Ensure compatibility with system voltage levels and thermal requirements before integration.

Digital Isolators Selection Notes

Select this component for designs requiring robust galvanic isolation in automotive environments. The unidirectional channel configuration suits simple signal transfer needs. Verify that the SSO-8 package fits the PCB layout constraints and that the 6000 Vrms rating exceeds the application's isolation requirements.

Digital Isolators Part Context

This part belongs to the Si86S6x family of low-power digital isolators. It shares architectural similarities with other members like the SI86S621EE-IS4 but differs in automotive qualification and packaging options. The series utilizes Skyworks' proprietary capacitive isolation technology for reliable performance.

Digital Isolators Replacement Considerations

SI86S621EE-IS4 is a non-automotive equivalent with similar electrical characteristics but lacks AEC-Q100 certification.
