MDC200-16 — Dual Diode Rectifier Module (200 A / 1600 V)

The MDC200-16 is a heavy-duty dual diode rectifier module engineered for high-power industrial systems that require dependable, continuous operation. Designed in an industry-standard 214F3/216F3 housing, the module delivers an average forward current rating of 200 A (case 100 °C) and a repetitive peak reverse voltage of 1600 V, making it well suited for rectifier stages in converters, inverters, and large DC supplies. 

Built for robust thermal and electrical cycling, the MDC200-16 supports very high surge capability (up to 7.5 kA surge forward current) and exhibits a low forward voltage — approximately 1.38 V at 600 A — which helps minimize conduction losses under heavy load. Its junction-to-case thermal resistance is low (about 0.210 °C/W), and the module can be supplied with an isolated mounting base rated up to 3000 V RMS for dependable insulation in high-voltage systems. These characteristics translate into higher efficiency, improved heat handling, and extended service life in demanding environments. 

The MDC200-16 is commonly deployed in motor drives, AC/DC motor controllers, UPS units, welding equipment, battery chargers and rectifier sections of power converters and soft starters where high current, high voltage and reliable cycling are essential. Its industrial-grade packaging, pressure-contact power terminals and compliance with common industry safety/ROHS requirements make the MDC200-16 a practical choice for designers who need a compact, serviceable rectifier module that integrates easily into existing power systems.
