The Powerex Inc. LDR31454 is a high-power SCR module designed for demanding applications requiring robust current handling and high voltage blocking. Featuring a series connection of two SCRs within a POW-R-BLOK™ module, this component offers a typical on-state current of 540A (average) and an RMS on-state current of 845A. Its off-state voltage rating is 1.4kV, ensuring reliable performance in high-voltage systems. The module is chassis mountable for efficient thermal management and operates across a wide temperature range of -40°C to 130°C. Key parameters include a gate trigger current (Igt) of 250mA and a hold current (Ih) of 300mA, with a maximum gate trigger voltage (Vgt) of 2.5V. Surge current capabilities are rated at 18000A and 17000A for 50Hz and 60Hz respectively. This module is commonly utilized in industrial motor control, power conversion, welding, and electric traction systems.
