SI88620ED-AS

Overview

The SI88620ED-AS is a general-purpose digital isolator from Skyworks Solutions, featuring two unidirectional channels in a 20-SOIC package. It operates on a supply voltage of 3 V to 5.5 V with a maximum data rate of 100 Mb/s and isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 18 ns (max), rise/fall times of 2.5 ns, and common mode transient immunity of 40 kV/µs. The device functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Capacitive coupling technology for signal transmission
• Unidirectional channel configuration
• High common mode transient immunity

Applications

• Industrial automation systems
• Medical equipment isolation
• Power metering circuits

Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm tape-and-reel packaging status versus tube packaging, as distributor listings may vary. Ensure the component meets required UL, CSA, VDE, and CQC certifications for your target market. Confirm moisture sensitivity level (MSL) handling requirements prior to assembly.

Selection Notes

Select this part for applications requiring robust capacitive isolation with high speed. The 2-channel unidirectional design suits simple signal transfer needs. Verify that the 100 Mbps data rate aligns with system timing constraints. Ensure the 20-SOIC footprint fits the PCB layout and thermal management strategy.

Part Context

Part of the Si88x2x series, designed for general-purpose isolation. It utilizes Skyworks' proprietary capacitive coupling technology to provide reliable signal transmission across isolation barriers without magnetic interference susceptibility.

Replacement Considerations

SI88620EC-ISR is listed as a parameter-equivalent substitute. Verify pinout compatibility and packaging differences (tube vs. reel) before substitution.
