SI88620BC-AS

Overview

The SI88620BC-AS is a two-channel unidirectional digital isolator from Skyworks Solutions, housed in a 20-pin 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, featuring an insulation voltage of 5000 Vrms and a common-mode transient immunity of 40 kV/µs. It functions within a temperature range of -40°C to +125°C without a shutdown pin.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology for signal transmission across isolated domains.
• Integrates a true automotive-grade process ensuring reliability under harsh environmental conditions.
• Delivers high-speed data integrity with low pulse width distortion characteristics.

Applications

• Automotive electronic control units requiring robust signal isolation
• Industrial communication interfaces needing high common-mode noise rejection
• Medical equipment requiring certified galvanic isolation

Procurement Notes

Verify the specific suffix AS against official Skyworks documentation to confirm package type and tape/reel specifications. Ensure compatibility with your system's voltage levels and thermal requirements before integration. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a two-channel unidirectional isolator with 5000 Vrms insulation is required. It is suitable for applications demanding high CMTI and operation up to 125°C. Consider the SOIC-20 footprint for PCB layout constraints and verify that the 100 Mbps speed meets your interface timing needs.

Part Context

This device belongs to the Si88620 series of CMOS digital isolators. It utilizes Skyworks' proprietary capacitive isolation technology to provide reliable signal transmission while blocking DC and low-frequency noise between isolated circuits.

Replacement Considerations

Check for SI88620BC-ASR as a reel-packaged alternative from the same family. Verify functional equivalence with other Skyworks 2-channel isolators if pinout and electrical specs match exactly.
