MBR50040CT

Diode Arrays Overview

The GeneSiC Semiconductor MBR50040CT is a silicon power Schottky diode in a Twin Tower package. It features a repetitive peak reverse voltage (VRRM) of 40 V and an average forward current (IF(AV)) of 500 A per package. The device operates within a junction temperature range of -55 to 150 °C. Key electrical characteristics include a maximum forward voltage of 0.75 V at 250 A and a thermal resistance (junction-case) of 0.30 °C/W per leg. The peak forward surge current is rated at 3500 A for an 8.3 ms half-sine pulse.

Diode Arrays Feature Summary

• Twin Tower package configuration for efficient mounting
• Not ESD sensitive, simplifying handling procedures

Diode Arrays Applications

• DC-DC converters
• Free-wheeling rectification in motor drives
• Power supply output rectification

Diode Arrays Procurement Notes

Verify the specific suffix 'R' if reversed leads are required, as standard parts have standard lead configurations. Confirm the exact voltage rating matches the application's 40 V requirement, distinguishing it from the 20 V or 30 V variants in the same series. Ensure thermal management solutions account for the 0.30 °C/W junction-to-case resistance to maintain safe operating temperatures under full load conditions.

Diode Arrays Selection Notes

Select this component when high current capacity and low forward voltage drop are critical for efficiency. The 40 V rating suits low-voltage, high-current applications where standard PN junctions would incur excessive losses. Consider the Twin Tower package for space-constrained PCB layouts requiring high current density. Evaluate thermal performance based on the specified junction-to-case resistance and ambient operating conditions.

Diode Arrays Part Context

This part belongs to the MBR50020CT through MBR50040CTR series of silicon Schottky diodes. The series offers varying reverse voltage ratings from 20 V to 40 V while maintaining a consistent 500 A average forward current rating. All variants share the same Twin Tower package and thermal characteristics, allowing for design flexibility across different voltage requirements without changing the physical footprint.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBR50020CT and MBR50030CT if lower voltage ratings are acceptable. Verify lead orientation for 'R' suffix versions against standard pinouts. Cross-reference with other manufacturers' 500 A, 40 V Schottky diodes in similar packages, ensuring thermal resistance and surge current capabilities meet or exceed the original specifications.
