SI8712BC-B-IS

Digital Isolators Overview

The SI8712BC-B-IS is a single-channel digital isolator from Skyworks Solutions, designed as an optocoupler replacement in an 8-SOIC package. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports data rates up to 15 Mb/s and features a maximum propagation delay of 60 ns. It operates on supply voltages between 3 V and 30 V, with a typical operating current of 1.7 mA. The component offers high common-mode transient immunity and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Capacitive coupling architecture for robust signal isolation
• Optocoupler replacement capability in standard SOIC-8 footprint
• High common-mode transient immunity for noise rejection
• Wide operating supply voltage range supporting multiple logic levels

Digital Isolators Applications

• Industrial automation control systems
• Power supply feedback loops
• General-purpose digital isolation interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'B' against official Skyworks documentation to confirm pinout compatibility and functional equivalence with legacy optocouplers. Ensure that the 8-SOIC package dimensions match the target PCB layout requirements. Confirm that the 3750 Vrms isolation rating meets the safety standards required for the intended application environment.

Digital Isolators Selection Notes

Select this component when a direct replacement for traditional optocouplers is needed without redesigning the PCB footprint. Consider the 15 Mb/s data rate limit for signal integrity requirements. Evaluate the 60 ns propagation delay against system timing constraints. Verify that the 3 V to 30 V supply range aligns with the available power rails in the design.

Digital Isolators Part Context

This part belongs to the Si8712 series of digital isolators manufactured by Skyworks Solutions. The series focuses on providing reliable isolation solutions that replace older LED-based optocouplers. The BC variant specifically denotes performance characteristics such as data rate and isolation voltage within the broader product family.
