MUR2040CT-BP

Overview

The MUR2040CT-BP is a 20 Amp Super Fast Glass Passivated Rectifier from Micro Commercial Components, rated for 400 Volts. It utilizes a common cathode configuration within a TO-220AB package. Key electrical parameters include a maximum reverse recovery time of 50ns and a peak forward surge current capability of 125A. The device operates with an average forward current of 20A at a case temperature of 90°C, featuring a typical thermal resistance of 2.0°C/W from junction to case.

Feature Summary

• Glass passivated chip construction ensures stability under varying environmental conditions.
• Super fast recovery characteristics minimize switching losses in high-frequency applications.
• High surge forward current capability provides robustness against transient load spikes.

Applications

• High frequency DC to DC converters
• Free wheeling diodes in inductive loads
• Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The standard BP designation indicates bulk packaging. Ensure procurement channels are authorized distributors to guarantee genuine parts with full traceability. Counterfeit prevention measures are strictly enforced by the manufacturer.

Selection Notes

Select this component when super fast recovery times are critical for circuit efficiency. The 400V rating suits medium voltage rectification tasks. Verify that the thermal management design accommodates the specified junction-to-case thermal resistance for reliable operation at rated currents.

Part Context

This part belongs to the MUR2010CT through MUR2060CT series, which shares identical physical dimensions and general electrical structures while differing in voltage ratings. The series is designed for general purpose rectification where speed and reliability are prioritized over ultra-low forward voltage drops found in Schottky alternatives.

Replacement Considerations

Direct replacements must match the 20A current rating, 400V blocking voltage, and TO-220AB package. Verify that substitute components offer equal or superior reverse recovery times to maintain circuit timing integrity.

FAQ

What is the maximum reverse recovery time for the MUR2040CT?

The maximum reverse recovery time is specified as 50ns under test conditions of IF=0.5A, IR=1.0A, and Irr=0.25A.

Does the -BP suffix change the electrical function of the device?

No, the -BP suffix only denotes the bulk packaging format (50pcs/Tube). It does not alter the electrical characteristics or performance of the semiconductor.

Is the MUR2040CT-HF available?

Yes, a halogen-free version is available upon request by adding the -HF suffix to the part number.
