MDS150/16 1600V 150A Three Phase Diode Rectifier Module
MDS150/16
The MDS150/16 is a rugged three-phase diode bridge rectifier module built to deliver high performance and reliability in industrial and commercial power electronics. With a direct DC output current of 150 A and a repetitive peak reverse voltage of 1600 V, this module handles substantial loads in rectification stages without compromising on thermal stability or safety. It is built for demanding environments where continuous, efficient conversion from AC to DC is required, such as in industrial power supplies, variable frequency drives (VFDs), battery chargers, and input rectifiers for inverters.
Designed for efficiency and durability, the MDS150/16 features low forward voltage drop, good surge current capability, and a robust housing (standard industrial “221H5” package in some variants) that allows for easy mounting and improved cooling. Its thermal resistance from junction to case is around 0.14 °C/W, helping maintain performance under sustained high load. It also offers reliable operation over a wide temperature range from −40 °C to +150 °C, ensuring stability in harsh industrial environments.
This rectifier module’s industrial and commercial applicability is wide: three-phase converters, motor drive "front ends", DC power supplies, chopper circuits, and any application requiring stable DC output with high current under high voltage. Its high surge current capability makes it forgiving during transient load spikes. Whether for new designs or replacing older rectifier bridges, the MDS150/16 combines performance, longevity, and cost-effectiveness.
