SI8630BT-AS

Digital Isolators Overview

The SI8630BT-AS is an automotive-grade digital isolator from the Skyworks si863x series, featuring three unidirectional channels with capacitive coupling technology. It operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 150 Mb/s. The device provides an insulation voltage of 5000 Vrms and withstands 10 kV surge capability. Key electrical parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a typical operating supply current of 4.6 mA. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in a 16-pin SOIC package.

Digital Isolators Feature Summary

Digital Isolators Procurement Notes

Verify the specific suffix AS against official Skyworks documentation to confirm automotive grade status and RoHS compliance. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Confirm moisture sensitivity level handling procedures during assembly to prevent damage. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Digital Isolators Selection Notes

Select this component when unidirectional isolation with high surge tolerance is required. Compare channel count and insulation voltage ratings against alternative models in the si863x family. Evaluate power consumption constraints relative to the 4.6 mA operating current. Consider the 150 Mb/s data rate limit for high-speed interface requirements.

Digital Isolators Part Context

This part belongs to the Skyworks si863x series of automotive digital isolators. It utilizes proprietary capacitive isolation technology to provide robust signal transmission across isolation barriers. The series is designed to meet stringent automotive reliability standards while offering low power consumption and high performance in compact packages.

Digital Isolators Replacement Considerations

Check for SI8630BB-AS or SI8630BD-AS as potential variants within the same series. Verify if the SI8631BT-AS offers compatible pinouts with different channel configurations. Consult official substitution guides to ensure functional equivalence without redesigning the circuit board.
