MBR7540R

Single Diodes Overview

The MBR7540R is a silicon power Schottky rectifier in the DO-5 stud mount package. It provides a repetitive peak reverse voltage of 40 V and an average forward current rating of 75 A per leg. The device features a maximum forward voltage of 1 V at 75 A and supports a peak forward surge current of 1000 A. Operating temperatures range from -55 °C to +150 °C, with a junction-to-case thermal resistance of 0.6 °C/W.

Single Diodes Feature Summary

• High surge capability for robust operation under transient conditions
• Non-sensitive design against electrostatic discharge events
• Standard polarity configuration with cathode stud connection

Single Diodes Applications

• Industrial power supply rectification
• DC-DC converter output stages
• Free-wheeling diodes in motor drive circuits

Single Diodes Procurement Notes

Verify the specific suffix designation during procurement to confirm terminal orientation. The 'R' variant indicates reversed polarity where the stud functions as the anode rather than the standard cathode configuration. Confirm mounting torque specifications and thermal interface requirements before integration into the final assembly.

Single Diodes Selection Notes

Select this component when high current handling and low forward voltage drop are required in a stud-mount form factor. Ensure the application voltage does not exceed the 40 V repetitive peak reverse voltage limit. Consider the thermal resistance characteristics for heatsink sizing to maintain junction temperature within the specified operating range.

Single Diodes Part Context

This part belongs to the MBR7520 through MBR7540R series of silicon power Schottky diodes manufactured by GeneSiC Semiconductor. The series offers various voltage ratings from 20 V to 40 V while maintaining a consistent 75 A current capacity across all variants in the DO-5 package style.

Single Diodes Replacement Considerations

Consult official datasheets for direct substitutes within the same voltage and current class. Verify pinout compatibility and thermal performance metrics before substituting.
