SI8710CD-AS

Digital Isolators Overview

The SI8710CD-AS is a single-channel digital isolator from Skyworks Solutions, designed as an optocoupler replacement. It features capacitive coupling technology with a 5000 Vrms isolation voltage and supports data rates up to 1 Mbps. The device operates on a supply voltage range of 3 V to 30 V, consuming 1.7 mA of operating current. It offers a propagation delay of 60 ns and a common-mode transient immunity of 20 kV/µs. Packaged in a 6-SOIC (0.295", 7.50mm Width) surface-mount format, it is qualified for automotive applications under AEC-Q100 standards.

Digital Isolators Feature Summary

• Provides robust 5000 Vrms isolation using proprietary CMOS capacitive coupling technology.
• Functions as a pin-compatible drop-in replacement for legacy optocouplers.
• Ensures high reliability with resistance to wear-out mechanisms typical of optical devices.

Digital Isolators Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Industrial control interfaces needing galvanic isolation
• General-purpose signal transmission across isolated boundaries

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm package dimensions and tape-and-reel specifications. Ensure the selected variant matches the required 6-SOIC footprint and automotive grade certification. Cross-reference the datasheet revision date to validate parameter accuracy before integration into production designs.

Digital Isolators Selection Notes

Select this component when a single unidirectional channel with 5000 Vrms isolation is required. It is suitable for replacing standard optocouplers where low power consumption and long-term reliability are critical. Consider the 1 Mbps data rate limit and 60 ns propagation delay for timing-sensitive applications.

Digital Isolators Part Context

This part belongs to the Si87xx series of digital isolators, which utilize CMOS isolation technology. The series is engineered to replace traditional optocouplers, offering superior performance in speed, power efficiency, and consistency while maintaining compatibility with existing board layouts.

Digital Isolators Replacement Considerations

Officially documented substitutes include other variants within the Si8710 family, such as the SI8710CD-B-IS or SI8710AC-B-IS, provided they meet the specific isolation voltage and package requirements.
