SKD 145/16 Three-Phase Bridge Rectifier — SEMIKRON (Danfoss)
The SKD 145/16 is a three-phase bridge rectifier module from SEMIKRON / Danfoss, built for industrial power-electronics applications that require reliable AC→DC conversion. It supports a maximum reverse voltage of 1.6 kV and a continuous load current rating of 140 A, making it suitable for input rectifiers in variable-frequency drives, DC motor field supplies, power supplies, and other heavy-duty systems.
The module features a compact SEMIPONT-5 housing with screw mounting and a low forward voltage drop to minimise conduction losses under sustained load. Its insulated case and good thermal transfer characteristics simplify PCB or plate mounting while helping manage heat in high-current applications. The SKD 145/16 also supports high surge currents (short-time forward impulse capability), making it tolerant of inrush and transient events commonly seen in industrial systems.
Designed for durability and ease of integration, the SKD 145/16 is UL-recognized and manufactured to SEMIKRON quality standards. It is widely stocked by authorized distributors and used by OEMs and service engineers as a replacement or for new designs where robust three-phase rectification is needed. Check the datasheet for absolute maximum ratings, thermal resistances, and mounting/dimension details before final design or replacement.
