SI86S620FE-IS4R

Digital Isolators Overview

The SI86S620FE-IS4R is a general-purpose digital isolator from the Si86S6x series, manufactured by Skyworks Solutions Inc. It features two unidirectional channels with capacitive coupling isolation technology. The device provides an insulation voltage of 6000 Vrms and supports data rates up to 150 Mb/s. It operates within a supply voltage range of 2.25 V to 5.5 V and includes a shutdown function. The component is housed in an 8-lead SOIC package (0.295 inch width) and is supplied in a reel format.

Digital Isolators Feature Summary

• Capacitive coupling isolation for high common-mode transient immunity
• Dual unidirectional signal transmission channels
• Integrated shutdown control for power management

Digital Isolators Applications

• Industrial automation communication interfaces
• Automotive electronic control units
• Power supply feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix IS4R confirms the reel packaging configuration. Confirm RoHS compliance status through official documentation. Check current moisture sensitivity level requirements against storage conditions. Ensure the 8-SOIC footprint matches the target PCB design constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this part when bidirectional I2C functionality is not required, as it offers only unidirectional channels. Compare propagation delay specifications against system timing budgets. Evaluate the 6000 Vrms insulation rating against application safety standards. Consider the SSO-8 or SOIC-8 package availability relative to assembly equipment capabilities.

Digital Isolators Part Context

This component belongs to the Si86S6x family of digital isolators. It shares the core capacitive isolation architecture with other variants in the series but differs in channel directionality and insulation ratings. The FE-IS4R designation specifies the unidirectional configuration and reel packaging distinct from tube-packed or bidirectional models.

Digital Isolators Replacement Considerations

SI86S620BC-ASR: Automotive grade variant with similar unidirectional topology but lower insulation rating. SI86S621FE-IS4: General purpose version with identical electrical characteristics but tube packaging instead of reel.
