SI86S620BC-IS

Digital Isolators Overview

The SI86S620BC-IS is a dual-channel digital isolator from Skyworks Solutions, designed for high-speed signal transmission with galvanic isolation. It features a maximum data rate of 150 Mbps per channel and operates with a supply voltage range of 3.0 V to 5.5 V on both the input and output sides. The device provides a typical common-mode transient immunity of 100 kV/µs and supports a working isolation voltage of 5000 Vrms. It is housed in an 8-lead SOIC package with wide body (SOP-8W) to ensure adequate creepage and clearance distances for safety standards compliance.

Digital Isolators Feature Summary

• Dual-channel architecture enabling independent signal isolation for two separate data lines
• High common-mode transient immunity ensuring reliable operation in noisy environments
• Wide operating supply voltage range supporting both 3V and 5V logic systems
• Compliant with international safety standards including UL, CSA, and VDE certifications

Digital Isolators Applications

• Industrial automation control systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for patient safety compliance
• Power electronics gate drive circuits for inverters and motor drives
• Data acquisition systems with mixed-signal ground separation requirements

Digital Isolators Procurement Notes

Verify the specific suffix 'BC-IS' matches your design requirements, as it denotes temperature grade and packaging details. Confirm that the SOP-8W package dimensions align with your PCB footprint. Ensure that the isolation voltage ratings meet the safety regulations applicable to your final product region. Check for RoHS compliance status if required by your manufacturing process.

Digital Isolators Selection Notes

Choose this component when dual-channel isolation is needed within a single package to save board space. Consider its 150 Mbps speed limit for applications not exceeding this data rate. Evaluate the 5000 Vrms isolation rating against your system's safety requirements. Compare power consumption characteristics if energy efficiency is a critical design constraint.

Digital Isolators Part Context

This part belongs to Skyworks' Si86xx family of digital isolators, which utilize capacitive coupling technology for signal transmission. The family offers various channel configurations and speed options to suit different application needs. The SI86S620BC-IS specifically targets applications requiring robust isolation with moderate data rates and standard package sizes.

Digital Isolators Replacement Considerations

Direct replacements may include other Skyworks Si8662 variants with similar pinouts and electrical characteristics. Verify compatibility with existing PCB layouts and firmware timing constraints when substituting. Cross-reference with competitors like Analog Devices or Texas Instruments only after confirming equivalent isolation and speed specifications.
