SI88620BD-AS

Overview

The SI88620BD-AS is a dual-channel unidirectional digital isolator from Skyworks Solutions, housed in a 20-pin SOIC package. It supports data rates up to 100 Mb/s with an insulation voltage of 5000 Vrms. The device operates on supply voltages between 3 V and 5.5 V, featuring a propagation delay of 18 ns and rise/fall times of 2.5 ns. It functions within a temperature range of -40°C to +125°C and includes no shutdown control.

Feature Summary

• Provides galvanic isolation for bidirectional signal transmission across separate power domains
• Utilizes CMOS technology to achieve low power consumption and high reliability
• Offers robust common-mode transient immunity for noise-sensitive environments

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix (AS) against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure compatibility with your system's voltage levels and thermal management needs before finalizing procurement decisions.

Selection Notes

Select this component when a dual-channel unidirectional isolator is required for applications demanding 5000 Vrms isolation. Consider the 20-pin SOIC package constraints and the 100 Mb/s data rate limit. Verify that the operating temperature range meets your environmental conditions.

Part Context

This part belongs to the Si886xx family of CMOS digital isolators. These devices are designed to replace traditional optocouplers, offering superior performance in speed, power, and size. The family provides various channel configurations and packaging options for diverse isolation needs.

Replacement Considerations

Check for direct substitutes like the SI88620BC-AS or SI88622BD-AS if channel directionality differs. Verify equivalent isolation ratings and package dimensions for cross-referencing.
