SI8736BC-IS

Digital Isolators Overview

The SI8736BC-IS is a single-channel unidirectional digital isolator from Skyworks Solutions, utilizing CMOS capacitive coupling technology. It provides an isolation voltage of 3750 Vrms and supports data rates up to 15 Mb/s with typical common-mode transient immunity of 25 kV/µs. The device operates on a supply voltage range of 2.5 V to 5.5 V, drawing a maximum operating current of 1.5 mA. Key timing parameters include a propagation delay of 50 ns and rise/fall times of 4 ns. It is housed in an SOIC-8 package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' corresponds to the tube packaging format as indicated in official distributor specifications. Confirm that the AEC-Q100 qualification status aligns with your target application's regulatory requirements. Ensure the SOIC-8 footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to confirm compatibility with your system's electrical characteristics.

Digital Isolators Selection Notes

Select this component when a single unidirectional channel with high-speed performance is required. The 15 Mb/s data rate suits moderate-speed digital isolation needs. Consider the 3750 Vrms isolation rating for safety-critical barriers. The low power consumption of 1.5 mA makes it suitable for energy-efficient designs. Verify thermal dissipation capabilities within the SOIC-8 package for your specific ambient temperature conditions.

Digital Isolators Part Context

This part belongs to the Si873x series of digital isolators from Skyworks Solutions. The series leverages proprietary CMOS isolation technology to replace traditional optocouplers. The SI8736BC-IS specifically offers a single-channel configuration optimized for unidirectional signal transfer. It represents a modern solution for galvanic isolation in mixed-signal environments.

Digital Isolators Replacement Considerations

The SI8736BC-ISR is a parametric equivalent variant available in tape-and-reel packaging. Designers may consider this alternative if automated surface-mount assembly processes require reel-based components instead of tubes. Electrical specifications remain consistent between the IS and ISR suffixes.
