SI88622BC-AS

Overview

The SI88622BC-AS is a two-channel unidirectional digital isolator from Skyworks Solutions, housed in a 20-SOIC package. It supports data rates up to 100 Mb/s with a propagation delay of 18 ns and rise/fall times of 2.5 ns. The device operates on a supply voltage between 3 V and 5.5 V, drawing 7.5 mA. It provides 5000 Vrms insulation and 40 kV/µs common-mode transient immunity. Operating temperatures range from -40°C to +125°C.

Feature Summary

• Provides high-speed bidirectional signal isolation for digital communication lines
• Features robust common-mode transient immunity for noise-sensitive environments
• Utilizes capacitive coupling technology for reliable signal transmission

Applications

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

Procurement Notes

Verify the specific suffix AS against official Skyworks documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity level requirements during storage and handling. Ensure the component meets AEC-Q100 standards if automotive application is intended.

Selection Notes

Select this model when unidirectional isolation is required for two channels. Compare against SI88622ED-IS if integrated DC-DC power isolation is needed instead of external supplies. Verify that the 20-SOIC footprint fits the PCB layout constraints. Ensure the 100 Mb/s speed rating matches the system communication requirements.

Part Context

This component belongs to the Si8862x series of general-purpose digital isolators. It is designed to replace traditional optocouplers in applications requiring higher reliability and lower power consumption. The series offers various channel configurations and insulation ratings to suit different interface needs.
