MBR20100CT

Diode Arrays Overview

The MBR20100CT is a Switch-mode Power Rectifier utilizing the Schottky Barrier principle with platinum barrier metal. It features a dual common cathode configuration in a TO-220 package, providing two independent diodes per unit. Each leg supports a peak repetitive reverse voltage of 100 V and an average rectified forward current of 10 A at a case temperature of 133°C. The device operates with a junction temperature range from -65°C to +175°C and offers a nonrepetitive peak surge current capability of 150 A.

Diode Arrays Feature Summary

• Guard-ring structure provides stress protection against transient overvoltage conditions.
• Majority carrier conduction results in low stored charge and minimal switching losses.
• Low instantaneous forward voltage drop ensures high efficiency and reduced power dissipation.
• Epoxy encapsulation meets UL 94 V-0 flammability ratings for enhanced safety.

Diode Arrays Applications

• High frequency inverters
• Free wheeling applications
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific ordering suffix when purchasing. The 'G' suffix indicates Pb-Free and RoHS compliance, while the base part number may denote standard packaging. Confirm the exact revision status of the datasheet (e.g., Rev. 1) to ensure alignment with current manufacturing specifications and mechanical dimensions.

Diode Arrays Selection Notes

Select this component for designs requiring robust thermal performance up to 175°C junction temperature. Ensure the application accounts for the 10 A per leg rating at elevated case temperatures rather than total device limits. Verify that the 100 V reverse voltage rating accommodates peak transient voltages in the target circuit topology.

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 MBR2080CT and MBR2090CT, all sharing identical current capabilities and physical package characteristics within the TO-220 form factor.

Diode Arrays Replacement Considerations

Direct substitutes include MBR2080CTG and MBR2090CTG from the same manufacturer family. These parts share identical electrical current ratings and package dimensions but differ only in their maximum repetitive reverse voltage specifications.
