SI88622EC-AS

Overview

The SI88622EC-AS is a general-purpose digital isolator from Skyworks Solutions, housed in a 20-SOIC package. It provides galvanic isolation with a rating of 5000 Vrms and supports data rates up to 100 Mb/s. The device features two unidirectional channels with zero forward channels. It operates on a supply voltage between 3 V and 5.5 V. Key electrical parameters include a propagation delay of 18 ns, rise/fall times of 2.5 ns, and pulse width distortion of 4.5 ns. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-voltage galvanic isolation for signal transmission between circuits operating at different potential levels.
• Utilizes capacitive coupling technology to ensure reliable data transfer without magnetic interference.
• Supports unidirectional signal flow across two isolated channels for specific interface requirements.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing safe patient isolation barriers
• Power electronics interfaces for gate drive applications

Procurement Notes

Verify the specific suffix AS against official Skyworks documentation to confirm tube packaging and lead-free status. Ensure compatibility with system voltage levels and thermal requirements before integration. Cross-reference datasheet revisions to avoid obsolete design-in risks.

Selection Notes

Select this component when unidirectional isolation is required for two-channel applications. Consider the 20-SOIC footprint for board space constraints. Evaluate the 5000 Vrms isolation rating against system safety standards. Confirm that the 100 Mb/s data rate meets communication speed needs.

Part Context

This part belongs to the Si8862x family of digital isolators. These devices are designed for industrial and automotive applications where high reliability and noise immunity are critical. The family offers various channel configurations and isolation ratings to suit diverse interface needs.

Replacement Considerations

SI88622EC-ASR is a reel-packaged alternative within the same series. Verify if tape-and-reel handling is acceptable for production processes. Other family members may offer different channel counts or isolation voltages.
