The DGT305SE18 from Dynex Semiconductor is a Gate Turn-Off Thyristor that is ideal for variable-speed AC motor drive inverters (VSD-AC), high voltage converters, choppers, welding, induction heating, DC/DC converters, uninterruptible power supply (UPS) applications. It has a break-over voltage of 1800 V and a break-over current of less than 700 A. This thyristor has a gate trigger voltage of up to 0.75 V and a gate trigger current of less than 1.2 A. It offers high voltage and surge current capability along with integrated fault protection (without fuses) for high reliability. The thyristor has a double-side cooled design for better temperature regulation. This gate turn-off thyristor ensures low noise emission that reduces acoustic cladding for various environmental requirements. It is available in a disc package that measures 42 x 15 mm.
