This data sheet provides the major ratings and characteristics for the IRK series MAGN-A-pak power modules. These modules use high voltage power diodes in two basic configurations. The semiconductors are electrically isolated from the metal base, allowing common heatsinks and compact assemblies to be built. They can be interconnected to form single phase or three phase bridges and the single diode module can be used in conjunction with the thyristor modules as a freewheel diode. These modules are intended for general purpose applications such as battery chargers, welders and plating equipment and where high voltage and high current are required (motor drives, etc.).
This document describes the International Rectifier IRK series of MAGN-A-pak standard recovery diode power modules. These high-voltage devices feature electrically isolated base plates, allowing for common heatsinks and compact assemblies in single-phase or three-phase bridge configurations.
The datasheet provides major ratings and characteristics including forward conduction parameters such as maximum average current up to 320A and RMS isolation voltage of 3000V. It also includes thermal specifications, mechanical dimensions, ordering information, and detailed graphs for power loss and surge current capabilities.
