PM50RLA120 Mitsubishi - Intelligent Power Module

PM50RLA120 Description

PM50RLA120 is a 1200 V, 50 A intelligent power module (IPM) made by Mitsubishi Electric. It is mostly used in small and mid-size AC drives and servo amplifiers, where built-in gate drive and protection save board space. Many of these parts are still in service in machines built years ago, and a direct replacement is often the fastest way to get one running again.
