SI86S620HE-AS4R

Digital Isolators Overview

The SI86S620HE-AS4R is a Skyworks Solutions automotive-grade digital isolator featuring two unidirectional channels with capacitive coupling. It provides a high insulation voltage of 6000 Vrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.25 V to 5.5 V, exhibiting a typical propagation delay of 13.5 ns. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in an SOIC-8 package.

Digital Isolators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust reliability
• High-voltage isolation capability via capacitive coupling technology
• Supports high-speed data transmission at rates up to 150 Mb/s

Digital Isolators Applications

• Automotive electronic control units requiring galvanic isolation
• Inverter gate drive circuits in electric vehicle powertrains
• Industrial communication interfaces demanding high noise immunity

Digital Isolators Procurement Notes

Verify the specific suffix AS4R indicates reel packaging configuration distinct from tube variants. Confirm AEC-Q100 automotive qualification status through official Skyworks documentation before integration. Ensure input voltage levels match the specified 2.25 V to 5.5 V operational range for reliable signal integrity.

Digital Isolators Selection Notes

Select this component when automotive certification and high isolation voltage are critical requirements. Compare against SI86S620BC-ASR for lower voltage options or SI86S621HE-AS4R for alternative channel configurations. Evaluate thermal performance and PCB layout constraints associated with the SOIC-8 footprint during design phase.

Digital Isolators Part Context

This part belongs to the Si86S6x series of automotive digital isolators from Skyworks Solutions. It complements other devices like the SI86S620BE-AS4 and SI86S621HE-AS4 within the same family, offering standardized interface solutions for high-reliability applications.

Digital Isolators Replacement Considerations

SI86S620HE-AS4R serves as the reel variant of the SI86S620HE-AS4 tube-packaged device. Verify pinout compatibility and electrical specifications against SI86S620BC-ASR if system voltage requirements differ.
