MBRT30040R

Diode Arrays Overview

The GeneSiC Semiconductor MBRT30040R is a silicon power Schottky diode module rated for a repetitive peak reverse voltage of 40 V and an average forward current of 300 A per package. It utilizes a three-tower isolation type package with an electrically isolated base plate. The device features a maximum instantaneous forward voltage of 0.70 V at Tj = 100 °C and a thermal resistance from junction to case of 0.40 °C/W per leg. Operating temperatures range from -55 °C to +150 °C, with a peak forward surge current capability of 2000 A.

Diode Arrays Feature Summary

• High surge capability designed for demanding power applications
• Three tower package configuration providing electrical isolation
• Electrically isolated base plate for safe mounting
• Not ESD sensitive for simplified handling

Diode Arrays Applications

• DC-DC converters
• Free-wheeling rectification in motor drives

Diode Arrays Procurement Notes

Verify the specific suffix 'R' indicates reversed leads as documented in the datasheet maximum ratings section. Confirm the 40 V rating aligns with system requirements. Check for RoHS compliance details on official documentation. Ensure thermal management solutions match the specified junction-to-case thermal resistance values for reliable operation under load conditions.

Diode Arrays Selection Notes

Select this component when high average current capacity and low forward voltage drop are required in a thermally efficient package. The three-tower design facilitates effective heat dissipation through the isolated base plate. Consider the 2000 A surge current rating for inrush protection scenarios. Verify that the 40 V reverse voltage provides adequate margin for the application's peak reverse stress levels.

Diode Arrays Part Context

This part belongs to the MBRT300 series of silicon power Schottky diodes, which includes variants ranging from 20 V to 40 V. The series shares common mechanical dimensions and thermal characteristics, differing primarily in voltage ratings. The 'R' suffix denotes a specific terminal configuration where leads are reversed compared to standard versions.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBRT30020R, MBRT30030R, and MBRT30035R, provided their lower voltage ratings meet the circuit requirements. Cross-brand replacements must match the 300 A current rating, 0.40 °C/W thermal resistance, and three-tower package dimensions.
