SI8620EC-AS

Digital Isolators Overview

The SI8620EC-AS is a dual-channel digital isolator from the Si86xx series, manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports unidirectional data transmission at speeds up to 150 Mb/s and operates within a supply voltage range of 2.5 V to 5.5 V. It features a propagation delay of 8 ns and functions reliably across an operating temperature range of -40°C to +125°C. The component is housed in an SOIC-NB-8 package.

Digital Isolators Feature Summary

• Capacitive coupling isolation for high-speed signal transmission
• Automotive-grade qualification ensuring reliability in harsh environments
• Wide operating supply voltage range supporting various logic levels

Digital Isolators Applications

• Automotive electronic control units
• Industrial communication interfaces
• Power supply feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm the exact tape-and-reel or tube packaging configuration. Ensure the automotive grade designation aligns with project requirements. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design specifications.

Digital Isolators Selection Notes

Select this component when high-speed isolation exceeding 100 Mbps is required alongside automotive reliability standards. Compare against the SI8620DB variant if lower insulation voltage (2500 Vrms) suffices for the application. Consider the SI8620AB series only if ultra-low power consumption at reduced data rates (1 Mb/s) is the primary design constraint.

Digital Isolators Part Context

This part belongs to the Skyworks Si86xx family of digital isolators, which replaces traditional optocouplers in modern designs. The EC suffix indicates automotive-grade qualification, distinguishing it from commercial variants. The family is characterized by low power consumption and high common-mode transient immunity compared to legacy isolation technologies.

Digital Isolators Replacement Considerations

SI8620EC-B-ISR: Same functional specifications but different packaging format.
