MUR2020CT

Overview

The Vishay MUR2020CT is an ultrafast recovery rectifier featuring a dual common cathode configuration with two independent 10 A legs. It utilizes FRED Pt® platinum-doped lifetime control technology to achieve a typical reverse recovery time of 25 ns and low forward voltage drop. The device supports a peak repetitive reverse voltage of 200 V, operates at junction temperatures up to 175 °C, and is housed in a TO-220AB package.

Feature Summary

• Ultrafast recovery characteristics enabled by platinum-doped life time control
• Low forward voltage drop for optimized efficiency
• High thermal stability with 175 °C operating junction temperature
• Designed for industrial level ruggedness and reliability

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 against the manufacturer's current documentation. Standard production versions utilize tube packaging containing 50 pieces. Lead-free variants are designated with the PbF suffix. Confirm RoHS compliance status and ensure the component meets industrial qualification requirements before integration into final designs.

Selection Notes

Select this component for circuits requiring fast switching speeds and high current handling capabilities. The dual common cathode topology allows for efficient bridge or center-tapped configurations. Ensure adequate heatsinking to manage thermal resistance, as the device supports high average forward currents per leg under rated conditions.

Part Context

This part belongs to the MUR series of ultrafast recovery rectifiers from Vishay High Power Products. The series is characterized by planar structure and optimized performance metrics for forward voltage and recovery time. It serves as a specialized solution for high-frequency power conversion applications where switching losses must be minimized.

Replacement Considerations

Consult official datasheets for direct substitutes within the MUR series or equivalent ultrafast rectifiers from other manufacturers. Verify that any replacement matches the 200 V rating, 2 x 10 A current capacity, TO-220AB package, and reverse recovery time specifications.
