SI8712CC-B-IS

Digital Isolators Overview

The SI8712CC-B-IS is a single-channel digital isolator from Skyworks Solutions, designed as an optocoupler replacement. It features capacitive coupling technology with a 3750 Vrms isolation voltage and operates within a supply range of 3 V to 30 V. The device supports data rates up to 1 Mbps with a propagation delay of 60 ns and a common-mode transient immunity of 20 kV/µs. It is housed in an 8-pin SOIC package, rated for operation between -40°C and +125°C, and meets AEC-Q100 automotive qualification standards.

Digital Isolators Feature Summary

• Provides unidirectional signal isolation using high-reliability capacitive coupling technology
• Functions as a pin-compatible drop-in replacement for legacy LED input optocouplers
• Delivers high common-mode transient immunity to ensure signal integrity in noisy environments

Digital Isolators Applications

• Industrial automation control systems requiring galvanic isolation
• Automotive electronics meeting AEC-Q100 reliability standards
• Power supply feedback loops and gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' against official Skyworks documentation to confirm reel packaging specifications. Ensure the component matches the required 3750 Vrms isolation rating for the target application safety standards. Confirm that the SOIC-8 package dimensions align with existing PCB footprints before finalizing procurement decisions.

Digital Isolators Selection Notes

Select this component when a single-channel, unidirectional isolator is required for general-purpose applications. It is suitable for designs needing robust noise immunity and compatibility with standard logic levels. Consider the 1 Mbps data rate limit and 60 ns propagation delay to ensure timing requirements are met within the system architecture.

Digital Isolators Part Context

This part belongs to the Si87xx series of digital isolators, which are engineered to replace traditional optocouplers. The series offers improved performance metrics including lower power consumption and higher reliability. The CC variant specifically denotes the 3750 Vrms insulation capability, distinguishing it from higher voltage BD variants within the same family.
