The SKKH570/16E is a high-current thyristor-diode module manufactured by Semikron, part of the well-established SKKH series. This module combines a thyristor (SCR) and a freewheeling diode in a single SEMIPAK package, delivering a continuous on-state current of 570A and a peak repetitive reverse voltage of 1600V. The SKKH570/16E is engineered for use in heavy-duty power conversion systems where robust thermal management and high reliability are paramount. Its isolated base plate ensures safe integration into larger power assemblies and heatsink configurations.

The SKKH570/16E is widely deployed across a broad spectrum of industrial and commercial power electronics applications. Common uses include DC motor drives, controlled rectifiers, AC-DC power converters, crane and hoist drive systems, industrial welding equipment, electrochemical processing, UPS systems, and regenerative braking applications. Its high voltage and current ratings make it especially suited for medium-voltage industrial drives and large-scale power supply designs where long-term operational reliability is critical.
