MBRB2545CT

MBRB2545CT Description

The MBRB2545CT is a high-performance Schottky diode array manufactured by Vishay General Semiconductor – Diodes Division. Designed for fast recovery applications (≤500ns) with a common cathode configuration, this device offers low forward voltage drop (820mV @ 30A) and high reverse voltage tolerance (45V). Packaged in a TO-263AB (D²PAK) surface-mount format, it is optimized for high-current rectification while minimizing power losses. With an average rectified current of 15A per diode and low reverse leakage (200µA @ 45V), it delivers efficiency in demanding circuits. Though marked obsolete, its REACH compliance and Moisture Sensitivity Level (MSL 1) ensure reliability in legacy designs.
