Powerex Inc. ND421825 is a dual SCR module designed for high-power applications. This POW-R-BLOK™ module features a series connection of an SCR and a diode, offering a robust solution for power control. It boasts a repetitive peak off-state voltage (VDRM) of 1800V and a continuous on-state current (IT(AV)) of 250A, with an RMS on-state current (IT(RMS)) of 393A. The non-repetitive surge current (ITSM) reaches 8800A at 60Hz. Gate trigger characteristics include a maximum gate trigger current (IGT) of 150mA and a maximum gate trigger voltage (VGT) of 3V. Operating within a temperature range of -40°C to 130°C (TJ), this chassis-mount module is suitable for demanding industrial environments, including power supplies, motor drives, and welding equipment.
