Semikron SKD60-12 Three-Phase Power Bridge Rectifier

Semikron SKD60-12 is a 60 A, 1.2 kV three-phase bridge rectifier module (diode bridge) in SEMIPONT2 packaging with five terminals. It provides three-phase full-wave rectification for DC links in industrial power electronics and is commonly used as the front-end rectifier in variable-speed drives and other power conversion equipment; the design is optimized for mounting on standard heatsinks with reliable isolation. Key specifications include a continuous forward current rating of 60 A, a peak repetitive reverse voltage of 1.2 kV (VRRM), and a surge forward current (IFSM) around 1 kA, making it suitable for handling transient startup currents in demanding applications. This compact, module-style bridge simplifies configurations by replacing discrete diodes and is widely employed in motor drives, power supplies, and battery charging systems where robust, maintenance-free rectification is required in a three-phase input topology.
