SI86S605AE-AS2

Digital Isolators Overview

The SI86S605AE-AS2 is an automotive-grade digital isolator from the Si86S6x series, manufactured by Skyworks Solutions. It features a 6.0 kVrms insulation voltage and utilizes capacitive coupling technology. The device provides two channels: one bidirectional I2C channel and one unidirectional channel, supporting data rates up to 1 Mb/s for I2C applications. It operates within a supply voltage range of 2.25 V to 5.5 V and functions reliably across a temperature range of -40°C to +125°C. Packaged in a wide-body SOIC-16 (SOIC-WB-16) surface-mount format, it includes shutdown functionality and meets AEC-Q100 qualification standards for automotive reliability.

Digital Isolators Procurement Notes

Verify the specific suffix AS2 against your bill of materials to ensure correct packaging and tape-and-reel specifications. Confirm that the SOIC-WB-16 package dimensions match your PCB footprint requirements. Check for any recent product change notifications regarding material or manufacturing site updates. Ensure design-in compliance with AEC-Q100 standards if required for your automotive application tier. Validate thermal management strategies for operation at maximum junction temperatures.

Digital Isolators Selection Notes

Select this component when high-voltage isolation is required for I2C interfaces in automotive systems. The combination of bidirectional I2C and unidirectional channels allows for flexible system architectures without additional components. Consider the wide operating temperature range for under-hood applications. Compare propagation delay and pulse width distortion specifications against timing requirements of the target protocol. Evaluate power consumption metrics relative to battery-operated constraints.

Digital Isolators Part Context

This part belongs to the Si86S6x family of automotive digital isolators designed specifically for I2C and SPI applications. It complements other variants like the SI86SS51BE-AS2 which offers different channel configurations. The family shares common capacitive isolation technology but varies in channel count, directionality, and insulation ratings. This specific model targets applications needing isolated I2C connectivity alongside general-purpose digital isolation.

Digital Isolators Replacement Considerations

Direct replacements may include other Skyworks Si86S6x variants with similar channel counts and insulation ratings. Verify pin-to-pin compatibility before substitution. Cross-reference with industry-standard isolators only if electrical parameters such as insulation voltage and data rate are fully matched. Ensure any substitute also holds AEC-Q100 certification for automotive use.
