SI8711CC-ASR

Digital Isolators Overview

The SI8711CC-ASR is a single-channel digital isolator from Skyworks Solutions, designed as an optocoupler replacement for automotive applications. It features capacitive coupling technology with a 3.75 kVrms isolation voltage and 20 kV/µs common-mode transient immunity. The device operates within a supply voltage range of 3 V to 30 V, supporting data rates up to 1 Mb/s. Key electrical parameters include a propagation delay of 60 ns, rise time of 15 ns, and fall time of 5 ns. It functions reliably across an extended temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides robust galvanic isolation via capacitive coupling technology
• Engineered specifically as a direct replacement for traditional optocouplers in automotive systems
• Delivers high common-mode transient immunity for reliable signal integrity in noisy environments

Digital Isolators Applications

• Automotive electronic control units (ECUs)
• Battery management systems (BMS)
• Motor control interfaces
• Charging station communication circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'ASR' against official Skyworks documentation to confirm it denotes the tape-and-reel packaging variant rather than the tube-packaged 'AS' version. Ensure that the automotive qualification status aligns with your specific application requirements by consulting the manufacturer's latest product change notifications and reliability reports.

Digital Isolators Selection Notes

Select this component when a single-channel isolator is required for automotive-grade applications demanding high reliability. Consider the 1 Mbps data rate limit and unidirectional signal path. Evaluate the SOIC-8 package constraints and ensure the operating temperature range meets the environmental conditions of the target system design.

Digital Isolators Part Context

This part belongs to the Si8711CC series of digital isolators. It utilizes Skyworks' proprietary silicon dioxide (SiO2) insulation technology. The series is positioned to replace legacy optocouplers, offering improved performance metrics such as faster switching speeds and lower power consumption while maintaining comparable isolation capabilities.

Digital Isolators Replacement Considerations

Official substitutes include other variants within the Si8711CC family, such as the SI8711CC-AS or SI8711CC-B-IS, provided they meet the same channel count and isolation voltage requirements.
