MURD610CTT4

Overview

The MURD610CTT4G is a SwitchMODE power rectifier manufactured by onsemi, designed for high-efficiency switching applications. It features a dual common cathode configuration housed in a D2PAK (TO-263) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 1000 V and an average forward rectified current of 6 A per diode. Key electrical characteristics include a typical forward voltage of 1.75 V at 6 A, a maximum non-repetitive peak surge current of 80 A, and a fast recovery time of 75 ns. The component operates within a junction temperature range of -65 °C to 175 °C.

Feature Summary

• SwitchMODE technology optimized for low conduction losses and high efficiency in hard-switching topologies
• Fast recovery characteristics with controlled soft recovery behavior to minimize electromagnetic interference
• High thermal performance enabled by the exposed tab D2PAK package design
• Lead-free construction compliant with RoHS standards

Applications

• High-frequency DC/DC converters
• Free-wheeling rectification in synchronous buck circuits
• Output rectification in flyback and forward power supplies
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the complete part number includes the 'G' suffix, indicating lead-free and halogen-free compliance as per onsemi specifications. Confirm the package designation matches the D2PAK form factor required for your PCB layout. Ensure the supplier provides official datasheets to validate the 1000V rating and 75ns recovery time parameters before integration into the design.

Selection Notes

Select this component when designing circuits requiring high voltage blocking capability combined with moderate current handling in a compact surface-mount footprint. The 1000V rating makes it suitable for primary-side rectification or high-voltage secondary stages. Compare the 75ns recovery time against slower standard recovery diodes if lower switching noise is not critical, or against ultra-fast variants if reduced EMI is a priority.

Part Context

This device belongs to onsemi's SwitchMODE family, which utilizes advanced processing techniques to achieve superior trade-offs between forward voltage drop and reverse recovery charge. The MURD series is engineered specifically for hard-switching applications where minimizing switching losses is essential for overall system efficiency and thermal management.

Replacement Considerations

Cross-reference with other onsemi SwitchMODE parts such as the MURB1660CTT4G for higher current requirements or the MURD410CTT4G for different current ratings. Verify that any substitute maintains the same D2PAK pinout and thermal pad configuration to ensure mechanical compatibility.
