MEK350-02DA IXYS - Diode Module

MEK350-02DA Description

MEK350-02DA is a 200 V, 356 A diode module made by IXYS. It is used in input rectifiers, freewheeling and clamping circuits, battery chargers and welding power sources. 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.
