MBRT50020R

Diode Arrays Overview

The GeneSiC Semiconductor MBRT50020R is a silicon power Schottky diode module featuring a Three Tower package with an electrically isolated base plate. It provides a repetitive peak reverse voltage of 20 V and supports an average forward current of 500 A per package. The device operates within a junction temperature range of -55 °C to +150 °C. Key electrical parameters include a maximum instantaneous forward voltage of 0.75 V at 250 A and a maximum thermal resistance from junction to case of 0.30 °C/W per leg. The 'R' suffix indicates reversed leads compared to standard configurations.

Diode Arrays Feature Summary

• High surge capability for robust transient handling
• Electrically isolated base plate for safety and mounting flexibility
• Not ESD sensitive for simplified handling

Diode Arrays Applications

• Low voltage high current DC-DC converters
• Free-wheeling rectification in synchronous buck circuits
• Power factor correction stages requiring low forward drop

Diode Arrays Procurement Notes

Verify the specific lead configuration required, as the 'R' suffix denotes reversed leads relative to the standard MBRT50020. Confirm that the 20 V rating aligns with the system's peak reverse voltage requirements. Ensure the cooling solution can manage the 0.30 °C/W thermal resistance to maintain junction temperatures within the specified -55 °C to +150 °C operating range during continuous 500 A operation.

Diode Arrays Selection Notes

Select this component when a low forward voltage drop is critical for efficiency in high-current applications below 20 V reverse stress. The Three Tower package allows for efficient heat dissipation through the isolated base plate. Compare against the MBRT50030R or MBRT50040R if higher voltage blocking is needed, noting that forward voltage characteristics remain consistent across the series.

Diode Arrays Part Context

This module belongs to the MBRT50020 thru MBRT50040R series of silicon power Schottky diodes. The family shares identical thermal and current ratings, differing primarily in their repetitive peak reverse voltage ratings which range from 20 V to 40 V. All variants utilize the same Three Tower isolation package design.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include the MBRT50030R and MBRT50040R, provided the circuit voltage does not exceed their respective 30 V and 40 V ratings. Verify pinout compatibility due to the reversed lead configuration of the 'R' variant.
