MBR3045CTP

Diode Arrays Overview

The MBR3045CTP is a discontinued Schottky barrier rectifier manufactured by Diodes Incorporated. It features a dual common cathode configuration housed in an ITO-220S package with an electrically isolated heat sink tab. The device supports a peak repetitive reverse voltage of 45V and provides a total average rectified output current of 30A, distributed as 15A per leg. Electrical characteristics include a maximum forward voltage drop of 0.65V at 15A and 25°C, and a non-repetitive peak forward surge current capability of 250A. The component operates within a temperature range of -65°C to +175°C.
