Single Diodes datasheet and documents for MBRB1045T4
Single Diodes Overview
The onsemi MBRB1045T4 is a discontinued switch-mode Schottky power rectifier designed for surface mount applications. It utilizes the Schottky barrier principle in a large metal-to-silicon power diode with epitaxial construction and oxide passivation. The device features a D2PAK-3 package (CASE 418B) and provides a peak repetitive reverse voltage of 45 V and an average rectified forward current of 10 A at a case temperature of 135 °C. It supports a nonrepetitive peak surge current of 150 A and operates within a junction temperature range of -65 °C to +175 °C.
