Powerex Inc. ND431225 is a dual Silicon Controlled Rectifier (SCR) module designed for high-power applications. This chassis-mount component features two SCRs in a series configuration within a POW-R-BLOK™ package. It offers a repetitive peak off-state voltage (VDRM) of 1.2 kV and a continuous on-state current (IT(AV)) rating of 250 A, with an RMS on-state current (IT(RMS)) of 393 A. The module exhibits a substantial surge capability, with an ItsM rating of 8800 A at 60 Hz. Gate trigger characteristics include a maximum gate trigger voltage (VGT) of 3 V and a maximum gate trigger current (IGT) of 150 mA. Operating reliably across a temperature range of -40°C to 130°C (TJ), this Powerex SCR module is utilized in demanding industrial sectors such as power conversion, motor control, and welding equipment.
