MBRB3030CTT4

Diode Arrays Overview

The MBRB3030CTT4 is a dual Schottky barrier rectifier manufactured by onsemi, housed in a D2PAK-3 (TO-263) surface-mount package. It features a common cathode configuration with two independent diodes sharing a single cathode terminal. The device is rated for a maximum repetitive peak reverse voltage of 30V and supports a total average forward rectified current of 30A. Key electrical characteristics include a maximum forward voltage drop of 670mV at rated current and a peak non-repetitive forward surge current capability of 200A. The component operates within a junction temperature range from -65°C to +175°C.

Diode Arrays Feature Summary

• Schottky barrier technology ensures low forward voltage drop and high energy efficiency during rectification.
• Common cathode dual configuration allows for efficient use of board space in power supply designs.
• High thermal stability supports operation at elevated junction temperatures up to 175°C.
• Robust surge current handling capacity protects against transient overloads in power circuits.

Diode Arrays Applications

• Output rectification in DC-DC converters
• Power management systems requiring low loss rectification
• Free-wheeling diodes in inductive load circuits

Diode Arrays Procurement Notes

Verify the exact part number suffix, as the provided model lacks the final 'G' often denoting RoHS compliance in onsemi's catalog. Confirm package dimensions match the D2PAK-3 specification. Ensure the supplier provides official datasheets confirming the 30A/30V ratings. Check for automotive qualification requirements if applicable to your design.

Diode Arrays Selection Notes

Select this component when a low-voltage, high-current synchronous or asynchronous rectification solution is needed. The D2PAK package offers superior thermal dissipation compared to smaller SMD packages. Consider the 670mV forward voltage drop impact on overall system efficiency. Verify that the 200A surge rating meets the inrush current demands of the specific application circuit.

Diode Arrays Part Context

This device belongs to onsemi's SWITCHMODE Power Rectifier family, designed for high-efficiency power conversion applications. The MBRB series utilizes advanced Schottky technology to minimize power losses. The TO-263 package is standard for medium-power discrete semiconductors requiring robust thermal performance and reliable surface-mount assembly.

Diode Arrays Replacement Considerations

Check for MBRB3030CTT4G as a potential equivalent with explicit RoHS certification. Verify pinout compatibility with existing PCB footprints. Ensure replacement parts maintain the same 30A current rating and 30V voltage withstand capability.
