The SKKH172/16E is a high-performance thyristor-diode module manufactured by Semikron, rated for 172A continuous current and 1600V repetitive peak off-state voltage. This SKKH-series module integrates one SCR (silicon-controlled rectifier) and one freewheeling diode in a single isolated package, making it ideal for half-wave or half-controlled bridge rectifier topologies. The module's robust construction and Semikron's proven semiconductor technology ensure reliable operation in demanding industrial environments.

The SKKH172/16E is widely used in industrial AC motor drives, soft starters, DC power supplies, battery chargers, and electrochemical process equipment. Its high voltage and current ratings make it suitable for medium-to-large power applications where controlled rectification and efficient energy conversion are critical. The isolated baseplate design simplifies thermal management and mechanical integration into standard heatsink assemblies.
