SI88622BD-ASR

Overview

The SI88622BD-ASR is a Skyworks Solutions digital isolator featuring two unidirectional channels in a 20-SOIC package. It operates on a 3 V to 5.5 V supply with a typical current of 7.5 mA. The device supports data rates up to 100 Mb/s and provides 5000 Vrms isolation voltage. Key electrical parameters include an 18 ns propagation delay, 2.5 ns rise/fall times, and 4.5 ns pulse width distortion. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed digital signal transmission across isolation barriers using capacitive coupling technology.
• Features robust common-mode transient immunity for reliable operation in electrically noisy environments.
• Supports general-purpose applications with unidirectional channel configuration and no shutdown functionality.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interfacing
• Power electronics control circuits

Procurement Notes

Verify the specific suffix ASR indicates reel packaging when sourcing. Confirm RoHS compliance status through official datasheets. Check for AEC-Q100 automotive qualification if required for your application. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component for designs needing two-channel unidirectional isolation with high CMTI. Compare against SI88622BC-ASR for identical electrical performance but different packaging formats. Consider thermal dissipation requirements given the SOIC-20 footprint and operating temperature range.

Part Context

Part of the Si8862x family of digital isolators from Skyworks Solutions. Designed for general-purpose isolation tasks where high reliability and speed are critical. Shares core specifications with other variants in the series differing primarily in package type or orientation.

Replacement Considerations

SI88622BC-ASR serves as a direct functional substitute with identical electrical characteristics. Verify package compatibility before substitution as both utilize the 20-SOIC form factor.
