SI8635BT-AS2R

Digital Isolators Overview

The SI8635BT-AS2R is an automotive-grade digital isolator from Skyworks Solutions, utilizing capacitive coupling technology. It features three unidirectional channels with a data rate of 150 Mb/s and a propagation delay of 8 ns. The device operates on a supply voltage between 2.5 V and 5.5 V, drawing 4.6 mA of working current. It provides 5000 Vrms isolation voltage and supports a common-mode transient immunity of 35 kV/µs. Operating temperatures range from -40°C to +125°C. The component is housed in a 16-SOIC package.

Digital Isolators Feature Summary

• Automotive qualification for high-reliability applications
• High common-mode transient immunity capability
• Ultra-low power consumption design
• Capacitive coupling isolation technology

Digital Isolators Applications

• Automotive electronic control units
• Inverter gate drive circuits
• Industrial communication interfaces
• Power metering systems

Digital Isolators Procurement Notes

Verify the specific suffix 'AS2R' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm automotive grade compliance through official Skyworks documentation. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification. Cross-reference pinout compatibility if substituting other SI863x series components.

Digital Isolators Selection Notes

Select this component when high isolation voltage and automotive reliability are required. The 3-channel unidirectional configuration suits applications needing isolated signal transmission in one direction only. Consider the 150 Mbps speed limit for bandwidth requirements. Evaluate thermal management needs given the SOIC-16 package and operating temperature range.

Digital Isolators Part Context

This part belongs to the SI863x family of digital isolators. It shares architectural similarities with SI8635BB-AS but offers higher isolation ratings. The 'BT' designation typically denotes automotive grade and specific performance characteristics within the Skyworks portfolio. It serves as a robust interface solution for noisy electrical environments.

Digital Isolators Replacement Considerations

SI8635BT-AS2 is a non-reel variant of the same functional device. SI8635BB-AS offers lower isolation voltage (2.5 kVrms) but similar channel count. Verify pinout and electrical specifications before substitution.
