SI8661EB-B-IUR

Digital Isolators Overview

The SI8661EB-B-IUR is a six-channel digital isolator from the Si866x series, manufactured by Skyworks Solutions Inc. It features unidirectional signal transmission with five forward and one reverse channel. The device utilizes capacitive coupling technology to provide an insulation voltage of 2500 Vrms. It supports data rates up to 150 Mb/s with a propagation delay of 8 ns. Operating on a supply voltage range of 2.375 V to 5.5 V, it functions within temperatures from -40 °C to +125 °C. The component is housed in a 16-SSOP package.

Digital Isolators Feature Summary

• Provides galvanic isolation via capacitive coupling for high noise immunity
• Supports unidirectional data transmission across six independent channels
• Designed for low power consumption applications requiring high reliability

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits for gate drive isolation

Digital Isolators Procurement Notes

Verify the specific suffix B-IUR against official Skyworks documentation to confirm the 16-SSOP package and reel packaging configuration. Ensure the 2500 Vrms insulation rating meets your system safety requirements. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when a six-channel unidirectional isolator with 2500 Vrms capability is required. Compare against the SI8661BD variant if higher 5 kV insulation is needed. Consider the QSOP-16 package option if lead-free tube packaging is preferred over the standard reel format for surface mount assembly processes.

Digital Isolators Part Context

This part belongs to the Si866x family of ultra-low power digital isolators. These devices are designed to replace traditional optocouplers in various interface applications. The family offers improved performance metrics including lower power consumption and higher common-mode transient immunity compared to legacy technologies.
