MUR1020CT

Overview

The MUR1020CT is a dual ultrafast recovery rectifier from Vishay, utilizing FRED Pt technology. It features a common cathode configuration with two independent anodes in a TO-220AB package. The device supports a peak repetitive reverse voltage of 200 V and provides a total average rectified forward current of 10 A (5 A per leg). Key electrical specifications include a maximum reverse leakage current of 10 µA at rated voltage and 25 °C, and a typical reverse recovery time of 25 ns under specific test conditions. The component operates within a junction temperature range of -65 to 175 °C.

Feature Summary

• Ultrafast recovery characteristics enabled by platinum-doped lifetime control for optimized switching performance
• Low forward voltage drop and low leakage current to minimize power dissipation
• Rugged planar structure designed for industrial level reliability
• RoHS compliant construction

Applications

• Output rectification stage of switch-mode power supplies (SMPS)
• Uninterruptible power supply (UPS) systems
• DC-to-DC converters
• Freewheeling diodes in low voltage inverters
• Chopper motor drives

Procurement Notes

Verify the specific ordering suffix when sourcing. The 'PbF' designation indicates lead-free terminations compliant with RoHS directives, whereas standard production versions may contain lead. Confirm the package style matches the required mounting configuration, as the series is available in multiple form factors including TO-220AB, D-PAK, and TO-262. Ensure technical validation is performed for the specific application requirements.

Selection Notes

Select this component for applications requiring high-frequency operation where minimizing switching losses is critical. The FRED Pt technology offers superior trade-offs between forward voltage and reverse recovery charge compared to standard ultrafast rectifiers. Consider the thermal resistance parameters and derating curves when designing heat sinking solutions for continuous high-current loads.

Part Context

This device belongs to the MUR series of ultrafast plastic rectifiers manufactured by Vishay High Power Products. The series utilizes advanced FRED Pt (Fast Recovery Epitaxial Diode Platinum) technology to achieve high efficiency and ruggedness. The MUR1020CT specifically denotes a 10 A rating and 200 V voltage class within the dual common cathode configuration.

Replacement Considerations

Cross-reference with other Vishay MUR series parts or equivalent ultrafast rectifiers from other manufacturers. Verify that substitute components match the 200 V reverse voltage, 10 A total current, and TO-220AB package dimensions. Ensure dynamic recovery characteristics are compatible with the target circuit's dIF/dt requirements.
