TD541S-40H5

Overview

The TD541S-40H5 is a digital isolator manufactured by Mornsun America, LLC. It features four channels with SPI interface type and capacitive coupling technology. The device provides 5000VDC isolation voltage and supports data rates up to 150Mbps. It includes an integrated isolated DC-DC converter for power supply. Key electrical parameters include a minimum common-mode transient immunity of 75kV/µs, maximum propagation delay of 13ns, and typical rise/fall times of 2.5ns. Operating temperature range is -40°C to 125°C.

Feature Summary

• Integrates an isolated DC-DC converter within the DFN package to replace discrete isolation power solutions.
• Provides high-speed signal transmission with 150Mbps data rate capability using capacitive coupling technology.
• Offers enhanced isolation performance with 5000VDC withstand voltage and 75kV/µs common-mode transient immunity.

Applications

• Industrial communication systems requiring galvanic isolation
• Motor control applications with high noise environments
• Medical equipment needing reinforced isolation barriers

Procurement Notes

Verify component authenticity through authorized Mornsun distributors. Confirm RoHS3 compliance status prior to integration. Check datasheet for latest revision updates regarding UL certification validity periods. Ensure proper handling procedures for moisture sensitivity level 3 components during storage and assembly processes.

Selection Notes

Select this model when integrated isolated power is required alongside signal isolation in space-constrained designs. Consider the 16-BDFN package dimensions for PCB layout optimization. Evaluate thermal management requirements given the integrated DC-DC converter functionality within the small form factor.

Part Context

Part of the TD541S-4xH(L)x series featuring enhanced isolation voltage and integrated DC-DC converters. This series replaces traditional discrete component isolation power solutions with smaller footprint alternatives. The TD541S-40H5 specifically offers four-channel unidirectional SPI-compatible isolation with integrated power conversion capabilities.

Replacement Considerations

TD541S-40H3 and TD541S-40L3 are parameter-equivalent substitutes from Mornsun America, LLC. Verify pin compatibility and electrical specifications before substitution. These alternatives maintain similar isolation characteristics while potentially differing in packaging or minor operational parameters.
