MBR2545CT

Diode Arrays Overview

The MBR2545CT is a Schottky barrier rectifier manufactured by Diodes Incorporated, housed in a TO-220AB case. It features a dual common cathode configuration with an average rectified output current of 30 A at a case temperature of +130°C and a peak repetitive reverse voltage of 45 V. The maximum forward voltage drop is 0.82 V at 15 A (+25°C) or 30 A (+25°C), while the peak reverse current is limited to 0.2 mA at rated DC blocking voltage (+25°C). The device supports a non-repetitive peak forward surge current of 150 A and operates within a junction temperature range of -65°C to +175°C.
