The DG858BW45 from Dynex Semiconductor is a Gate Turn-Off Thyristor that offers excellent turn-off capability, thereby resulting in reduced equipment size and weight. It has a break-over voltage of 4500 V and a break-over current of less than 3000 A. This thyristor has a gate trigger voltage of up to 1.2 V and a gate trigger current of less than 4 A. It provides high voltage and surge current handling capability and supports double-side cooling, which improves equipment lifecycle and reliability. This GTO provides fault protection without requiring additional fuses. It ensures low noise emission that reduces acoustic cladding to suit various environmental requirements. This thyristor is available in a disc package that measures 120 x 27 mm and is ideal for choppers, induction heating, DC-DC converters, high-voltage converters, variable speed AC motor drive inverters (VSD-AC), UPS, and welding applications.
