MUR2020CT

Overview

The MUR2020CT is a super fast recovery rectifier manufactured by Good-Ark Semiconductor. It features a dual common cathode configuration with two silicon elements in a TO-220-AB package. The device supports a maximum repetitive peak reverse voltage of 200 V and a total average forward rectified current of 20 A at case temperature 105°C, or 10 A per diode leg. Key electrical parameters include a maximum reverse recovery time of 35 ns, a peak forward surge current of 125 A, and a maximum instantaneous forward voltage of 1.10 V at 10 A and 25°C. Thermal resistance from junction to case is typically 2.0 °C/W per leg.

Feature Summary

• FRED (Planar) wafer construction for high efficiency operation
• Low forward voltage drop resulting in low power losses
• Plastic package meets Underwriters Laboratory Flammability Classification 94V-0

Applications

• High frequency inverters
• Free wheeling applications
• Polarity protection circuits

Procurement Notes

Verify the specific package variant required for the design, as the MUR2020CT denotes the standard TO-220-AB leaded package while the MUR2020FCT indicates the ITO-220-AB insulated flange mount version. Confirm that the component complies with RoHS standards and check the manufacturer's documentation for any specific handling or soldering temperature limits during assembly processes.

Selection Notes

Select this component for designs requiring fast switching capabilities and low reverse recovery charge. Ensure the thermal management strategy accounts for the specified junction-to-case thermal resistance values. Verify that the operating ambient and case temperatures remain within the -55°C to +150°C range to maintain reliability and prevent performance degradation under load.

Part Context

This part belongs to the MUR series of super fast recovery rectifiers produced by Good-Ark Semiconductor. The series utilizes FRED planar wafer technology to achieve superior switching speeds compared to standard rectifiers. The MUR2020CT specifically addresses applications needing robust current handling and rapid recovery characteristics in a durable plastic encapsulated form factor.

Replacement Considerations

Cross-reference with other 20A, 200V super fast recovery diodes in the TO-220-AB package. Verify pinout compatibility and ensure equivalent or better specifications for reverse recovery time and forward voltage drop before substitution.
