DG858DW45 Image

The DG858DW45 from Dynex Semiconductor is a Gate-Turn-Off Thyristor 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 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 supports cooling on both sides for effective temperature regulation and high reliability. This thyristor offers excellent turn-off capability that allows for 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 120 x 27 mm.
