SI8630ET-IS

Digital Isolators Overview

The SI8630ET-IS is a unidirectional digital isolator from Skyworks Solutions, featuring three forward channels and zero reverse channels. It utilizes capacitive coupling technology to provide an isolation voltage of 5000 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns. It operates within a supply voltage range of 2.5 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-SOIC-Wide (7.50 mm wide) surface-mount format, it includes a 10 kV surge capability.

Digital Isolators Feature Summary

Digital Isolators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging and 'IS' denotes the SOIC-Wide package variant. Confirm AEC-Q100 qualification status if automotive application is required, as standard ET-IS variants may differ from BD-ASR automotive grades. Check moisture sensitivity levels and reflow soldering profiles against IPC standards before assembly.

Digital Isolators Selection Notes

Select this component when three unidirectional channels are required with 5000 Vrms isolation. Consider the 150 Mb/s data rate limit and 8 ns propagation delay for timing constraints. Ensure the 16-SOIC-Wide footprint fits the PCB layout. Compare against SI8630BD-ASR if automotive certification is mandatory, or SI8631BT-IS for different delay characteristics.

Digital Isolators Part Context

This part belongs to the si863x series of digital isolators from Skyworks Solutions. It shares the core capacitive coupling architecture with other members like the SI8631 and SI8635 but differs in channel count and specific electrical parameters. The series is designed for robust performance in noisy environments where reliable signal transmission across isolation barriers is critical.
