SI88620BC-ASR

Overview

The SI88620BC-ASR is a general-purpose digital isolator from Skyworks Solutions, featuring two unidirectional channels in a 20-SOIC package. It supports data rates up to 100 Mb/s with a propagation delay of 18 ns and pulse width distortion of 4.5 ns. The device operates on a supply voltage range of 3 V to 5.5 V and provides an insulation voltage of 5000 Vrms. It exhibits a common-mode transient immunity of 40 kV/µs and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology.
• Features unidirectional signal transmission for simplified interface design.
• Includes integrated DC-DC converter capability for isolated power generation.

Applications

• Industrial automation systems requiring robust signal isolation.
• Medical equipment needing high-voltage isolation safety.
• Power electronics interfaces for motor control applications.

Procurement Notes

Verify the specific suffix 'ASR' indicates reel packaging versus 'AS' tube packaging when sourcing. Confirm RoHS compliance status through official Skyworks documentation. Ensure the selected variant matches the required channel count and insulation voltage specifications for the target application environment.

Selection Notes

Select this component for designs requiring unidirectional isolation with moderate data rates. Compare against SI88621 variants if bidirectional communication or integrated power conversion is needed. Verify thermal performance requirements against the specified operating temperature range of -40°C to +125°C.
