MUR20020CTR

Overview

The MUR20020CTR is a silicon super fast recovery diode module from the MUR200 series, manufactured by GeneSiC Semiconductor. It features a Twin Tower package with screw mount installation and supports an average forward current of 200 A per leg. The device offers a repetitive peak reverse voltage range up to 200 V, with a maximum instantaneous forward voltage of 1.0 V at 100 A. It exhibits a maximum reverse recovery time of 75 ns and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• High surge capability with a peak forward surge current rating of 2000 A per leg.
• Non-ESD sensitive design suitable for robust industrial environments.
• Twin Tower package configuration providing efficient thermal dissipation.

Applications

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

Procurement Notes

Verify the specific part number suffix against official documentation, as variations may exist between standard and reversed lead configurations. Confirm that the component meets required RoHS compliance standards before integration. Ensure proper handling procedures are followed during installation to maintain the integrity of the screw mount terminals and the Twin Tower housing structure.

Selection Notes

Select this module for applications requiring high average forward current and fast switching speeds. The 75 ns reverse recovery time makes it suitable for high-frequency operations. Verify that the system's thermal management can handle the specified junction-to-case thermal resistance. Ensure the operating voltage does not exceed the 200 V repetitive peak reverse voltage limit under all transient conditions.

Part Context

This component belongs to the MUR200 series of silicon super fast recovery diodes. The series includes variants with different voltage ratings, such as 50 V, 100 V, and 200 V options. All models in this family share similar physical dimensions and electrical characteristics regarding current capacity and recovery speed, differing primarily in their blocking voltage specifications.

Replacement Considerations

Direct substitutes include other MUR200 series modules like the MUR20020CT. When replacing, ensure the new component matches the Twin Tower package type and screw mount requirements. Verify that the replacement maintains the same 200 A current rating and 75 ns reverse recovery time to preserve circuit performance.

FAQ

What is the difference between the MUR20020CT and MUR20020CTR?
