SI8635BD-ASR

Digital Isolators Overview

The SI8635BD-ASR is an automotive-grade digital isolator featuring three unidirectional channels with capacitive coupling technology. It provides 5000 Vrms isolation voltage and supports data rates up to 150 Mb/s. The device operates on a supply voltage range of 2.5 V to 5.5 V, drawing a typical operating current of 4.6 mA. Key electrical parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a common mode transient immunity of 60 kV/µs. It functions within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Digital Isolators Feature Summary

• Automotive-grade reliability for harsh environments
• High-speed signal transmission with low power consumption
• Robust insulation against high voltage transients

Digital Isolators Applications

• Automotive battery management systems

• Motor drive interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'ASR' to confirm reel packaging and automotive qualification status. Ensure compatibility with SOIC-16 footprint requirements. Cross-reference datasheet revision history for any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for automotive applications. The 3-channel configuration suits multi-signal interfaces. Consider the 150 Mb/s data rate limit and 60 kV/µs CMTI for noise immunity needs. Verify that the 2.5 V to 5.5 V supply range aligns with system power rails.

Digital Isolators Part Context

Part of the Si863x series, designed for high-reliability isolation in automotive electronics. Utilizes Skyworks' proprietary capacitive coupling technology to replace traditional magnetic transformers, offering smaller form factors and improved performance in high-frequency applications.

Digital Isolators Replacement Considerations

SI8635BD-AS: Same functional specifications but in tape-and-reel packaging instead of tube. SI8630BD-ASR: Similar 3-channel unidirectional isolator but with lower surge ratings compared to the SI8635 series.
