SI86S640FE-IS2

Digital Isolators Overview

The SI86S640FE-IS2 is a Skyworks Solutions automotive-grade digital isolator featuring four unidirectional channels with up to 6.0 kVrms isolation capability. It utilizes capacitive coupling technology and operates within a wide supply voltage range of 2.25 V to 5.5 V. The device supports data rates from DC to 150 Mbps and offers high common-mode transient immunity. Packaged in a 16-SOIC format, it requires no start-up initialization, making it suitable for robust industrial and automotive signal isolation applications.

Digital Isolators Feature Summary

• Provides up to 6.0 kVrms insulation strength for enhanced safety
• Supports high-speed data transmission up to 150 Mbps
• Operates without the need for start-up initialization sequences

Digital Isolators Applications

• Automotive telematics systems

• Power electronics gate drive isolation

Digital Isolators Procurement Notes

Verify that the specific suffix FE-IS2 matches the required package type and tape-and-reel configuration for your assembly line. Confirm that the 6.0 kVrms isolation rating aligns with your system's safety standards and regulatory requirements. Ensure compatibility with the specified 2.25 V to 5.5 V supply voltage range during design validation.

Digital Isolators Selection Notes

Select this component when high isolation voltage and high-speed data transfer are critical. It is ideal for designs requiring four isolated channels in a compact SOIC package. Consider its automotive-grade reliability for harsh environments. Compare against lower isolation variants if voltage stress is minimal, or higher speed options if data rates exceed 150 Mbps.

Digital Isolators Part Context

This part belongs to the Si86S6x series of automotive digital isolators from Skyworks Solutions. It complements other family members like the SI86S640BC-AS1R by offering higher isolation ratings. The series focuses on providing reliable signal separation in noisy electrical environments while maintaining small form factors for modern PCB layouts.

Digital Isolators Replacement Considerations

Direct substitutes include the SI86S640FE-IS2R (reel variant) and SI86S640EE-IS2 (tube packaging). Verify pinout compatibility and isolation voltage ratings before swapping. Ensure thermal performance and package dimensions match the existing footprint.
