TD541S-43H3

Overview

The TD541S-43H3 is a digital isolator from Mornsun America, LLC, featuring four channels with an integrated isolated DC-DC converter. It utilizes capacitive coupling technology and operates within a supply voltage range of 4.75V to 5.25V. The device supports data rates up to 150Mbps and offers a withstand voltage of 3.75kV rms. It is housed in an ultra-small, ultra-thin chip-scale DFN package, suitable for surface mount applications.

Feature Summary

• Integrates an isolated DC-DC converter to simplify power supply design
• Utilizes capacitive coupling technology for signal transmission
• Features an ultra-small, ultra-thin chip-scale DFN package

Applications

• General purpose digital isolation
• Industrial communication systems
• Medical equipment signal isolation

Procurement Notes

Verify the specific channel configuration (3 inputs/1 output) against system requirements. Confirm that the 3.75kV rms isolation rating meets safety standards. Ensure the operating temperature range aligns with environmental conditions. Check RoHS compliance status before integration.

Selection Notes

Select this component when space constraints require a compact DFN package. The integrated isolated power supply reduces external component count. Verify compatibility with 3.3V logic levels if applicable. Consider the 150Mbps data rate for high-speed interface needs.

Part Context

This part belongs to the TD541S-4xH(L)x series, which combines digital isolation with integrated power conversion. It is designed for applications requiring robust signal integrity in electrically noisy environments while minimizing board space through its small form factor.

Replacement Considerations

TD541S-43H5 is a parameter-equivalent alternative within the same series.
