MUR2040FCT

Overview

The Good-Ark MUR2040FCT is an ultrafast recovery rectifier featuring a planar FRED wafer construction and TO-220-AB package. It supports a maximum repetitive peak reverse voltage of 400 V and a maximum average forward rectified current of 20 A at Tc=105°C. The device exhibits an ultrafast maximum reverse recovery time of 35 ns, with a peak forward surge current capability of 125 A. Operating junction temperature ranges from -55 to +150 °C, and the thermal resistance from junction to case per leg is 4.0 °C/W.

Feature Summary

• Ultrafast recovery time for high efficiency
• Low forward voltage drop reducing power loss
• Planar FRED wafer construction
• UL certified plastic package with 94V-0 flammability rating

Applications

• High frequency switching power supplies
• Free wheeling diodes in DC-DC converters
• Inverter circuits requiring fast recovery characteristics

Procurement Notes

Verify the specific suffix 'FCT' corresponds to the TO-220-AB package variant when ordering. Confirm that the thermal resistance value of 4.0 °C/W applies to your specific configuration, as the datasheet distinguishes this from the CT variant's 2.0 °C/W. Ensure compliance with the 260°C maximum soldering temperature limit for 10 seconds during assembly processes.

Selection Notes

Select the MUR2040FCT when a TO-220-AB surface-mount compatible package is required alongside 20 A current handling. Compare the 4.0 °C/W junction-to-case thermal resistance against system cooling capabilities. Consider the 35 ns reverse recovery time for applications demanding minimal switching losses at high frequencies.
