SI8710BC-B-ISR

Digital Isolators Overview

The SI8710BC-B-ISR is a single-channel digital isolator from Skyworks Solutions, housed in an 8-SOIC package. It supports data rates up to 15 Mb/s with a propagation delay of 60 ns and common-mode transient immunity of 35 kV/µs. The device operates on supply voltages between 3 V and 30 V, drawing 1.7 mA. It provides 3750 Vrms isolation voltage and functions within a temperature range of -40°C to +125°C. Certified under AEC-Q100 standards, it utilizes capacitive coupling for signal transmission.

Digital Isolators Feature Summary

• Capacitive coupling technology ensures robust signal integrity across the isolation barrier.
• AEC-Q100 qualification confirms suitability for automotive electronic applications.
• High common-mode transient immunity protects against noise interference.

Digital Isolators Applications

• Automotive gate driver circuits
• Industrial motor control systems
• General-purpose isolated communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'B' indicates the correct insulation rating and package variant. Confirm the 'ISR' designation matches the required reel or cut-tape packaging format. Ensure the component meets AEC-Q100 requirements if deployed in automotive contexts. Cross-reference the datasheet revision date to confirm current specifications.

Digital Isolators Selection Notes

Select this model when a single channel with 15 Mb/s speed and 3750 Vrms isolation is required. Consider the 8-SOIC footprint for PCB layout constraints. Evaluate the 1.7 mA supply current against power budget limits. Verify that the unidirectional polarity aligns with the signal flow direction in the target circuit design.

Digital Isolators Part Context

This component belongs to the Si871x family of general-purpose digital isolators. It shares architectural similarities with other devices in the series but differs in channel count and specific electrical ratings. The family emphasizes low power consumption and high reliability for industrial and automotive environments.

Digital Isolators Replacement Considerations

Check for direct substitutes within the Si871x series that match the 8-SOIC package and 15 Mb/s rate. Verify pin compatibility and isolation voltage levels before swapping components. Ensure any alternative part maintains AEC-Q100 certification if automotive use is intended.
