TD541S-43H5

Overview

The TD541S-43H5 is a digital isolator from Mornsun America, LLC, featuring four channels with a 5000VDC isolation voltage. It supports data rates up to 150Mbps and offers a common mode transient immunity of 75kV/µs. The device includes an integrated isolated power supply and operates within a temperature range of -40°C to 125°C. It utilizes capacitive coupling technology and is housed in a 16-BDFN package.

Feature Summary

• Integrated isolated DC-DC converter for self-powered operation
• High-speed signal transmission capability up to 150Mbps
• Robust noise immunity with high common mode transient rejection

Applications

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

Procurement Notes

Verify the specific suffix 'H5' against official Mornsun documentation to confirm pinout and electrical characteristics. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for obsolescence notices as the component may be designated for non-new designs.

Selection Notes

Select this component when a single-chip solution providing both signal isolation and isolated power generation is required. Ensure the 150Mbps data rate meets system timing requirements. Verify that the 16-BDFN package dimensions fit the PCB layout constraints and thermal management needs.

Part Context

This part belongs to the TD541S-4xHx series of digital isolators. It is designed for applications needing reliable signal transmission across isolation barriers while eliminating the need for external isolated power supplies. The series emphasizes compact size and high reliability.

Replacement Considerations

Official parameter-equivalent substitutes include TD541S-43H3, TD541S-43L3, and TD541S-43L5. Verify pin compatibility and specific electrical tolerances before substitution.
