The DG408BP45 from Dynex Semiconductor is a Gate Turn off Thyristor that is ideal for variable-speed AC motor drive inverters (VSDAC), uninterruptable power supplies, high-voltage converters, hoppers, welding, induction heating, and DC/DC converter applications. It has a break-over voltage of 4500 V and a break-over current of less than 1000 A. This thyristor has a gate trigger voltage of up to 1 V and a gate trigger current of less than 1.5 A. It supports cooling on both sides for effective temperature regulation and high reliability. This thyristor offers excellent turn-off capability that allows a reduction in equipment size and weight. It exhibits low noise emission characteristics, which results in reduced acoustic cladding to cater to various environmental requirements. It is available in a disc package that measures 63.5 x 27 mm.
