MBRB20200CT

Diode Arrays Overview

The MBRB20200CT is a dual Schottky barrier rectifier manufactured by onsemi, designed for high-frequency switching power supplies and converters. It features a 200 V reverse voltage rating and a continuous forward current of 20 A per diode in a TO-263 (D2PAK) surface-mount package. The device utilizes platinum barrier metal technology to achieve low forward voltage drop and improved performance at frequencies ranging from 250 kHz to 5.0 MHz. Key electrical specifications include a maximum repetitive peak reverse voltage of 200 V, a maximum average forward rectified current of 20 A, and a non-repetitive peak forward surge current capability of 150 A. The component operates within a junction temperature range of -55°C to 175°C.

Diode Arrays Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and compliance status. Ensure the ordering part number matches the required thermal and mechanical specifications for the target PCB layout. Confirm RoHS and halogen-free status if environmental compliance is mandatory for the assembly process.

Diode Arrays Selection Notes

Select this component for designs requiring efficient rectification at high frequencies up to 5 MHz. The TO-263 package offers robust thermal performance for high current applications. Verify that the circuit design accounts for the parallel connection requirement of terminals 1 and 3 to achieve full 20 A rating.
