TD541S-42H5

Overview

The TD541S-42H5 is a reinforced digital isolator manufactured by Mornsun America, LLC. It features four channels with a data rate of 150Mbps and 5000VDC isolation voltage. The device includes an integrated isolated DC-DC converter 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 compact design
• High common-mode transient immunity of 75kV/µs
• Reinforced digital isolation technology

Applications

• Industrial automation systems
• Data acquisition modules
• Isolated communication interfaces

Procurement Notes

Verify the specific channel configuration (3 inputs, 1 output) against system requirements. Confirm RoHS3 compliance and MSL rating during integration. Check current product status as it may be subject to availability changes.

Selection Notes

Select this component when high-speed SPI communication requires galvanic isolation with integrated power conversion. Ensure the 16-BDFN footprint fits the PCB layout constraints.

Part Context

Part of the TD541S series offering digital isolation with integrated power supplies. Designed for applications requiring robust signal transmission across isolation barriers without external magnetic components.

Replacement Considerations

TD541S-42L5 offers parameter equivalence with potential pinout or specification variations requiring verification.
