SI86S642EC-IS1R

Digital Isolators Overview

The SI86S642EC-IS1R is a Skyworks Solutions digital isolator featuring four unidirectional channels with capacitive coupling technology. It provides an isolation voltage rating of 3750 Vrms and supports data rates up to 150 Mbps. The device offers a common-mode transient immunity (CMTI) of 100 kV/µs, ensuring reliable signal transmission in electrically noisy environments. Packaged in a 16-SOIC format, it operates within a specified temperature range suitable for industrial applications.

Digital Isolators Feature Summary

• Four-channel unidirectional signal isolation using robust capacitive coupling architecture
• High common-mode transient immunity rated at 100 kV/µs for noise rejection
• Supports high-speed data transmission with a maximum rate of 150 Mbps

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Power management circuits with high-voltage separation needs
• Communication interfaces in noisy electromagnetic environments

Digital Isolators Procurement Notes

Verify the specific suffix IS1R against official Skyworks documentation to confirm reel packaging and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements as stated in the datasheet. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit products. Confirm that the 16-SOIC package dimensions align with your PCB footprint design constraints prior to ordering.

Digital Isolators Selection Notes

Select this component when four independent unidirectional isolation paths are required within a single package. The 150 Mbps data rate makes it suitable for standard industrial communication protocols. Consider the 3750 Vrms isolation barrier for safety-critical applications. Evaluate the 100 kV/µs CMTI specification if the application involves rapid voltage transients or high-frequency switching noise.

Digital Isolators Part Context

This device belongs to the Skyworks Si86S6x series of digital isolators. It utilizes proprietary silicon dioxide (SiO2) isolation technology to provide electrical isolation between circuits. The series is designed to replace traditional optocouplers, offering improved performance, smaller form factors, and better consistency in manufacturing.

Digital Isolators Replacement Considerations

Direct replacements may include other models from the Si86S6x family with compatible channel counts and isolation ratings. Verify pinout compatibility and functional equivalence before substituting. Consult the Skyworks replacement guide for validated cross-reference options.
