MURP20040CT

Overview

The MURP20040CT is an ultrafast rectifier manufactured by onsemi, designed for high-efficiency power conversion applications. It features a 200-ampere average forward current rating and supports reverse voltage capabilities up to 400 volts. The device utilizes PowerTAP II packaging technology, which integrates the ultrafast switchmode rectifier into a compact surface-mount form factor. This design facilitates improved thermal performance and reduced footprint compared to traditional through-hole alternatives, making it suitable for demanding industrial and consumer power supply environments.

Feature Summary

• Ultrafast recovery characteristics enable high-frequency switching with minimal reverse recovery charge.
• PowerTAP II package provides enhanced thermal dissipation and robust mechanical stability.
• Designed for high surge current capability to withstand transient load conditions.

Applications

• High-frequency DC/DC converters
• Industrial power supplies
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct voltage and current ratings. Confirm that the ordering part number matches the required PowerTAP II package variant. Check for RoHS compliance status if environmental regulations apply to the target assembly. Ensure the supplier provides traceable documentation from onsemi or authorized distributors.

Selection Notes

Select this component when high current handling and fast switching speeds are critical for efficiency. The PowerTAP II package is preferred over standard TO-220 variants for space-constrained designs requiring superior heat transfer. Evaluate thermal resistance parameters in the context of the specific heatsinking strategy employed in the final equipment design.

Part Context

This device belongs to the MURP series of ultrafast rectifiers from onsemi, which are engineered for use in hard-switching applications. The series leverages advanced silicon planar technology to achieve low forward voltage drops while maintaining high reverse blocking capabilities. It represents a transition toward more compact, surface-mount solutions in high-power rectification markets.

Replacement Considerations

Direct substitutes include other 200A ultrafast rectifiers in compatible packages such as the MURP20060CT for higher voltage requirements. Verify pinout compatibility and thermal pad dimensions before substituting with components from different manufacturers.
