MF300K04F3-BP

Overview

The MF300K04F3-BP is a silicon Fast Recovery Epitaxial Diode (FRED) module manufactured by Micro Commercial Components. It features a single configuration with screw mount installation and an F3 package. The device supports a maximum repetitive reverse voltage of 400 V and a maximum average forward current of 300 A at a case temperature of 125°C. Key electrical parameters include a typical forward voltage of 1.05 V at 150 A, a peak reverse recovery time of 90 ns at 25°C, and a surge current capability of up to 3000 A for half-cycle sine waves. The module operates within a junction temperature range of -40°C to +150°C.
