SI86SS51BE-AS2R

Digital Isolators Overview

The SI86SS51BE-AS2R is a Skyworks Solutions digital isolator featuring capacitive coupling technology. It provides 4 unidirectional channels with a voltage isolation rating of 6000 Vrms and supports data rates up to 150 Mbps. The device includes an SPI-compatible interface with a reset function, designed for automotive applications. It operates within a supply voltage range of 2.25 V to 5.5 V and functions across temperatures from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates SPI-compatible communication protocols with a dedicated reset control feature
• Utilizes capacitive coupling architecture for high-speed signal transmission
• Provides robust common-mode transient immunity for reliable operation in noisy environments

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial systems utilizing SPI-based sensor networks
• High-voltage power monitoring circuits demanding galvanic isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration distinct from tube variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling procedures are strictly followed during assembly due to the sensitivity of capacitive isolation structures.

Digital Isolators Selection Notes

Select this component when SPI protocol compatibility and hardware reset functionality are required alongside high-voltage isolation. Compare channel count and propagation delay specifications against system timing requirements. Validate that the 6000 Vrms isolation barrier meets the safety standards applicable to the target application environment.

Digital Isolators Part Context

This part belongs to the Si86SS5x series of automotive-grade digital isolators. It shares the core capacitive isolation technology found in other Skyworks interface devices but is specifically optimized for SPI applications. The family offers various channel configurations and insulation ratings tailored for diverse industrial and automotive needs.

Digital Isolators Replacement Considerations

Direct substitutes include SI86SS51BE-AS2 for non-reel packaging or SI86SM41BE-AS2 for similar channel counts without SPI features. Verify pinout compatibility and electrical parameter alignment before swapping components in existing designs.
