MBRB20H100CTHE3/81

Diode Arrays Overview

The MBRB20H100CTHE3/81 is a dual common cathode high voltage Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes High Barrier Technology to deliver improved high-temperature performance and low leakage current. The device features a D2PAK (TO-263AB) surface-mount package, rated for a maximum repetitive peak reverse voltage of 100 V and a total maximum average forward rectified current of 20 A (10 A per diode). Key electrical characteristics include a peak forward surge current capability of 250 A and a maximum junction temperature of 175 °C.

Diode Arrays Feature Summary

• High Barrier Technology ensures enhanced thermal stability and reduced leakage at elevated temperatures
• Guardring structure provides robust overvoltage protection capabilities
• Low forward voltage drop design minimizes power loss and increases overall system efficiency
• Capable of high-frequency operation suitable for demanding switching applications

Diode Arrays Applications

• High frequency rectification in switching mode power supplies
• Freewheeling diodes in DC/DC converter circuits
• Polarity protection applications requiring low leakage

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. The 'M3' designation indicates halogen-free commercial grade material, while 'E3' denotes RoHS compliance. Confirm that the 'I' suffix corresponds to tape and reel delivery with the specified base quantity. Ensure the component meets JESD 201 class 1A whisker test standards if required by the application environment.

Diode Arrays Selection Notes

Select this component when a surface-mount solution is required for high-efficiency power conversion. The D2PAK package offers lower thermal resistance compared to through-hole alternatives like TO-220AB. Consider the 175 °C junction rating for environments where case temperatures may exceed standard limits. Verify that the 100 V reverse voltage rating aligns with the peak inverse voltage present in the target circuit topology.

Diode Arrays Part Context

This part belongs to the MBRB20H100CT series within Vishay's portfolio of dual common cathode Schottky rectifiers. It shares core electrical specifications with the MBR20H100CT and MBRF20H100CT variants, differing primarily in the mechanical package configuration. The series is designed for general-purpose high-current applications requiring fast recovery and low forward voltage characteristics.

Diode Arrays Replacement Considerations

Direct functional equivalents include the MBRB20H100CT-M3/I variant from the same manufacturer family. Cross-package replacements such as the MBRF20H100CTGHE3/4 or MBR20H100CT-E3/45 are available but require evaluation of thermal management and mounting constraints due to different housing geometries.
