MacMic MMF200ZB040DK1C 200A 400V Rectifier Module
MMF200ZB040DK1C
The MMF200ZB040DK1C is a high-performance DUTO-FRED (dual ultra-fast recovery freewheeling & rectifier) module from MacMic, engineered to deliver outstanding forward current capability with minimal losses. Rated at 400 V blocking voltage and 200 A average forward current, this module is designed for heavy industrial and commercial power electronics tasks. It excels where high current rectification with efficiency and thermal stability is essential—such as in power factor correction (PFC), high-power converters and inverter front-ends, uninterruptible power supplies, and industrial welders.
Built for durability, the MMF200ZB040DK1C features low forward voltage drop (≈1.1-1.3 V at high current), ultrafast reverse recovery time, low leakage current, and a low-inductance package. These characteristics help reduce switching losses, improve overall efficiency, and ensure reliable performance during transient loads. The module also handles high surge currents (non-repetitive surge current ≈ 1000 A for 1/2 cycle at 50-60 Hz) and operates over a wide junction temperature range (−40 °C to +125 °C), which makes it suitable even in harsh conditions.Â
In industrial and commercial environments, the MMF200ZB040DK1C is especially useful in applications like ultrasonic welders, plating power supplies, inverter systems, and converters & choppers. Its soft-recovery attributes make it a strong candidate for circuits that must control voltage spikes and reduce electromagnetic interference (EMI). Whether used in new designs or as a replacement in demanding rectifier stages, this module blends efficiency, robustness, and long service life.
