MDS300A1600V – Three Phase Bridge Rectifier Module
The MDS300A1600V is a three-phase bridge rectifier module designed for industrial and commercial power electronics applications. With a direct output current rating of 300 A and a maximum repetitive peak reverse voltage (V_RRM) of 1600 V, this module provides efficient and reliable AC-to-DC conversion. Its robust construction and thermal design make it suitable for inverter welders, PWM converters, DC power supplies, and other high-power systems requiring stable performance.
The module features a high isolation voltage of 2500 VAC for safe operation in industrial environments. It operates effectively across a temperature range from -40°C to +150°C, with a rated junction temperature of 150°C. A low thermal impedance of 0.16°C/W allows efficient heat dissipation, reducing the risk of thermal overload. The compact design and standard screw terminal mounting simplify integration into various power systems.
The MDS300A1600V also offers low forward voltage drop (approximately 1.1 V at 400 A), high surge current capability (4800 A for 10 ms), and low reverse leakage current (10 mA at 150°C). These characteristics improve system efficiency and reliability, making the module suitable for applications requiring high-power rectification.
