SI86S610BC-IS

Digital Isolators Overview

The SI86S610BC-IS is a single-channel digital isolator from Skyworks Solutions, utilizing capacitive coupling technology to provide electrical isolation. It features a unidirectional signal path with an insulation voltage rating of 3750 Vrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.5 V to 5.5 V and includes a shutdown function for power management. Packaged in an 8-pin SOIC-NB (narrow body) surface-mount package, it is designed for high reliability with a common-mode transient immunity of 100 kV/µs.

Digital Isolators Feature Summary

• Capacitive coupling isolation architecture ensures robust signal transmission across the isolation barrier.
• Integrated shutdown pin allows for active power reduction when the device is not in use.
• High common-mode transient immunity protects against noise-induced errors in electrically noisy environments.

Digital Isolators Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power electronics gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'BC' and 'IS' during procurement to ensure correct package type and tape-and-reel packaging configuration. Confirm that the 3750 Vrms insulation rating meets the safety requirements of the target application. Check for AEC-Q100 qualification if automotive compliance is required, although this specific part number should be cross-referenced with official datasheets for exact automotive status.

Digital Isolators Selection Notes

Select this component when a single unidirectional isolated channel is sufficient for the design. It is suitable for applications needing moderate data speeds up to 150 Mbps. Consider the narrow-body SOIC-8 package constraints for PCB layout. Ensure the operating voltage aligns with the 2.5 V to 5.5 V input range. Evaluate the need for the shutdown feature versus always-on operation for power budgeting.

Digital Isolators Part Context

This part belongs to the Si86S6x series of digital isolators, which are characterized by their low power consumption and small form factor. The series utilizes Skyworks' proprietary capacitive isolation technology, offering advantages over traditional optocouplers such as higher speed, better temperature stability, and longer lifespan. The SI86S610BC-IS represents a specific configuration within this family optimized for single-channel applications.

Digital Isolators Replacement Considerations

Direct replacements may include other single-channel capacitive isolators from Skyworks or competitors like Analog Devices or Texas Instruments. Verify pin compatibility, insulation voltage ratings, and data rate specifications before substitution. Ensure the replacement package matches the 8-SOIC footprint to avoid PCB redesign.

Digital Isolators FAQ

What is the common-mode transient immunity (CMTI) of the SI86S610BC-IS?

The SI86S610BC-IS has a common-mode transient immunity of 100 kV/µs, ensuring reliable operation in high-noise environments.
