MBR2080CT

Diode Arrays Overview

The MBR2080CTG is a dual common cathode Schottky barrier rectifier from onsemi, utilizing platinum barrier metal technology. It provides a total average forward current of 20 A (10 A per diode leg) with a peak repetitive reverse voltage of 80 V. The device features a low forward voltage drop and high surge capacity, supporting an operating junction temperature up to 175°C. Packaged in a TO-220 case, it is designed for high-efficiency applications requiring low power loss.

Diode Arrays Feature Summary

• Guard-ring structure provides stress protection against overvoltage conditions.
• Majority carrier conduction results in low stored charge and fast switching characteristics.
• Epoxy casing meets UL 94 V-0 flammability rating for enhanced safety.

Diode Arrays Applications

• Switch-mode power supplies
• Free-wheeling rectification in DC-DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific ordering suffix when sourcing components. The 'G' suffix indicates a lead-free and RoHS-compliant version, which is standard for current production. Confirm that the package style matches the required TO-220 dimensions and pin configuration before integration into the design.

Diode Arrays Selection Notes

Select this component for applications requiring high efficiency at low voltage drops. Ensure thermal management accounts for the specified junction-to-case thermal resistance. Verify that the peak repetitive reverse voltage rating exceeds the maximum circuit voltage to prevent breakdown during operation.

Diode Arrays Part Context

This device belongs to the MBR20 series of Switch-mode Power Rectifiers manufactured by onsemi. The series includes variants with different reverse voltage ratings, such as the MBR2090CTG and MBR20100CTG, all sharing the same 20 A total current capability and physical package specifications.

Diode Arrays Replacement Considerations

Compatible substitutes within the same family include the MBR2090CTG and MBR20100CTG. These parts share identical electrical current ratings and mechanical dimensions but offer higher reverse voltage capabilities of 90 V and 100 V, respectively.
