Siemens Semikron SKKD120 Thyristor Power Module

Siemens Semikron SKKD120/12 is a SEMIPACK-series power module that houses two series-connected diodes in a half-bridge arrangement. This SKKD configuration provides a compact, standalone diode path for rectification and freewheeling in power-conversion circuits, making it a practical choice for rectifier bridges and DC-link stages in motor drives, power supplies, and other high-power applications. The module is designed to integrate with standard SEMIPACK footprints, enabling straightforward assembly with compatible heat sinking and enclosure interfaces. In diode-based topologies, SKKD120/12 delivers a robust, modular solution that simplifies interconnects and maintenance while fitting within common industrial power-electronics layouts.
