SI8712CC-B-ISR

Digital Isolators Overview

The SI8712CC-B-ISR is a unidirectional digital isolator from the Si8712CC series, manufactured by Skyworks Solutions. It features capacitive coupling technology with a 3.75 kVrms isolation voltage and supports data rates up to 1 Mb/s. The device operates within a supply voltage range of 3 V to 30 V, consuming 1.7 mA of working power current. Key electrical parameters include a propagation delay of 60 ns, a maximum rise time of 15 ns, and a maximum fall time of 5 ns. It is qualified under AEC-Q100 standards and functions reliably across an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides optical coupler replacement functionality using LED input emulation
• Utilizes capacitive coupling for high-speed signal transmission
• Features AEC-Q100 qualification for automotive reliability

Digital Isolators Applications

• Automotive electronic control units (ECUs)
• Industrial motor control systems
• General-purpose isolated communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' corresponds to the required tape-and-reel packaging format, as package variations exist within the product family. Confirm that the 3.75 kVrms isolation rating meets the safety requirements of the target application. Ensure the unidirectional channel configuration aligns with the system's signal flow direction. Cross-reference the AEC-Q100 qualification status if the design mandates automotive-grade components.

Digital Isolators Selection Notes

Select this component when a single-channel, unidirectional isolation barrier is required between circuits. The 1 Mb/s data rate suits applications not demanding high-bandwidth transmission. Consider the SOIC-8 package dimensions for PCB layout constraints. The wide operating temperature range allows deployment in harsh environments without additional thermal management.

Digital Isolators Part Context

This part belongs to the Si87xx family of digital isolators, which replaces traditional optocouplers. The CC suffix indicates a specific insulation class and performance tier within the series. The ISR suffix denotes the reel-based packaging variant, distinguishing it from cut-tape or tube options available for other SKUs in the same functional family.

Digital Isolators Replacement Considerations

SI8712BD-B-IM is a related part number within the same manufacturer portfolio, offering similar isolation characteristics but potentially differing in package type or specific electrical tolerances.
