SI86SO21EC-ASR

Digital Isolators Overview

The SI86SO21EC-ASR is a dual-channel digital isolator from Skyworks Solutions, designed for automotive applications. It features two unidirectional channels with inverting outputs, housed in an SOIC-NB-8 package. The device supports data rates up to 150 Mbps and provides an insulation voltage of 3750 Vrms. It operates within a supply voltage range of 2.5 V to 5.5 V and functions across a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Automotive-grade qualification for reliable operation in harsh environments
• Capacitive coupling isolation technology for signal transmission
• Inverting output configuration for specific logic interface requirements

Digital Isolators Applications

• Automotive powertrain control systems
• Battery management systems in electric vehicles
• Industrial motor drive interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'ASR' indicates reel packaging and automotive grade status against the manufacturer's official documentation. Confirm that the SOIC-NB-8 package dimensions match your PCB footprint requirements. Ensure the inverting output polarity aligns with your system logic design before procurement.

Digital Isolators Selection Notes

Select this component when automotive certification and high common-mode transient immunity are required. The dual-channel unidirectional design suits isolated gate driver or sensor interfaces. Consider the inverting output characteristic as it affects signal path logic compared to non-inverting variants in the same series.

Digital Isolators Part Context

This part belongs to the Si86SO2x series of digital isolators. It shares the capacitive isolation architecture with other members but is distinguished by its automotive rating and specific channel configuration. The SOIC-NB-8 package offers a compact solution for space-constrained automotive electronics.

Digital Isolators Replacement Considerations

Direct substitutes include SI86SO21EC-IS for tube-packaged equivalents. Verify pinout compatibility and insulation voltage ratings when cross-referencing with other Skyworks isolator models.
