SI88620EC-AS

Overview

The SI88620EC-AS is a general-purpose digital isolator manufactured by Skyworks Solutions Inc. It features two unidirectional channels housed in a 20-SOIC package. The device supports data rates up to 100 Mb/s with a maximum propagation delay of 18 ns. It provides an isolation voltage of 5000 Vrms and operates within a supply voltage range of 3 V to 5.5 V. The component functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed digital signal isolation via capacitive coupling technology
• Ensures robust noise immunity with specified common-mode transient rejection capabilities
• Supports bidirectional communication through dedicated reverse channel configuration

Applications

• Industrial automation control systems
• Power electronics monitoring interfaces
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 20-SOIC form factor. Confirm that the unidirectional channel configuration meets the design requirements, as this variant differs from bidirectional counterparts in the same series.

Selection Notes

Select this component when unidirectional signal transmission is required between isolated domains. The 20-SOIC package offers a compact solution for space-constrained designs. Consider the 100 Mb/s data rate limit and 18 ns propagation delay for timing-sensitive applications. Verify that the 5000 Vrms isolation rating satisfies the safety standards of the target application environment.

Part Context

This part belongs to the Si8862x family of digital isolators from Skyworks Solutions. The family utilizes proprietary capacitive isolation technology to provide high reliability and low power consumption. The SI88620EC-AS specifically denotes a two-channel unidirectional variant within this portfolio, designed for general-purpose isolation tasks.

Replacement Considerations

SI88620BC-ASR is listed as a parametric equivalent in distributor databases. Verify pinout and electrical characteristics match before substitution. Other variants in the Si8862x series may offer different channel counts or directions.
