SI86S621HE-IS4R

Digital Isolators Overview

The SI86S621HE-IS4R is a general-purpose digital isolator from Skyworks Solutions, featuring two unidirectional channels. It provides 6000 Vrms isolation voltage and supports data rates up to 10 Mbps with a common-mode transient immunity of 150 kV/µs. The device operates within a supply voltage range of 2.25 V to 5.5 V and functions across an industrial temperature range of -40°C to +125°C. Packaged in an 8-SOIC (0.295 inch width) tape and reel format, it utilizes capacitive coupling technology for signal transmission.

Digital Isolators Feature Summary

• Provides galvanic isolation between input and output circuits using capacitive coupling technology
• Supports high-speed digital signal transmission with defined propagation delay characteristics
• Features robust common-mode transient immunity to maintain signal integrity in noisy environments

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits demanding high-voltage separation

Digital Isolators Procurement Notes

Verify the specific suffix HE against official Skyworks documentation to confirm package type and reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles during assembly. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 8-SOIC footprint matches your PCB design requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required and unidirectional signal flow suffices. Consider the 6000 Vrms rating for applications exceeding standard 5000 Vrms isolation needs. Evaluate the 10 Mbps data rate against system timing requirements. Verify that the SOIC-8 package dimensions fit within the available board space constraints.

Digital Isolators Part Context

This part belongs to the Si86S6x series of digital isolators from Skyworks Solutions. The series focuses on providing reliable isolation for general-purpose applications. The SI86S621 variant specifically offers dual-channel unidirectional isolation. The IS4R suffix indicates the specific packaging configuration used for automated assembly processes.

Digital Isolators Replacement Considerations

Check Skyworks datasheets for direct pin-compatible alternatives within the Si86S6x family. Verify if other manufacturers offer equivalent 6000 Vrms unidirectional isolators with matching channel counts and package styles.
