SI86S600AC-IS

Digital Isolators Overview

The SI86S600AC-IS is a Skyworks Solutions digital isolator featuring two bidirectional channels with capacitive coupling technology. It provides an insulation voltage of 3750 Vrms and supports data rates up to 10 Mb/s, specifically optimized for I2C protocols. The device operates within a supply voltage range of 3 V to 5.5 V and draws a typical operating current of 5.4 mA. It exhibits a propagation delay of 20 ns with rise and fall times of 4 ns. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +125°C in an SOIC-Narrow-8 package.

Digital Isolators Feature Summary

• Capacitive coupling isolation barrier ensures high reliability and immunity to electromagnetic interference compared to optical alternatives.
• Integrated on-chip architecture supports bidirectional I2C communication with low power consumption.
• Automotive-grade qualification (AEC-Q100) guarantees performance stability across extended industrial temperature ranges.

Digital Isolators Applications

• Automotive telematics and infotainment systems requiring isolated I2C buses
• Industrial automation controllers needing robust signal isolation
• Medical equipment interfaces demanding high safety isolation standards

Digital Isolators Procurement Notes

Verify the specific suffix IS indicates tape and reel packaging if required by automated assembly lines, as tube packaging may be standard for other variants. Confirm AEC-Q100 automotive qualification status matches project requirements. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-reference pinout compatibility with existing PCB layouts before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when bidirectional I2C isolation is required with moderate data rates up to 10 Mb/s. The 3750 Vrms rating suits general industrial and automotive applications where cost-effective isolation is prioritized over higher voltage ratings. Consider the SOIC-8 footprint constraints and ensure thermal management aligns with the 220 mW power dissipation limit during continuous operation.

Digital Isolators Part Context

Part of the Si86S6x family of automotive-grade digital isolators designed for high-reliability environments. This series integrates capacitive isolation technology to replace traditional optocouplers, offering superior speed and longevity. The SI86S600AC-IS specifically targets I2C bus isolation needs in compact form factors.

Digital Isolators Replacement Considerations

SI86S600AE-IS4 offers higher 6.0 kVrms insulation but uses SSO-8 packaging. SI8600AC-B-IS provides similar functionality but lacks explicit automotive qualification documentation in provided sources. Verify pinout and electrical parameters against these alternatives before substitution.
