The DDKT3400A 56-65 is a high-performance phase control thyristor designed for large power converters, DC and AC switches, and both active and passive inverters. Featuring a center amplifying gate and a durable metal case with ceramic insulation, this thyristor offers superior thermal management and high reliability. It can handle up to 3500A of average on-state current, a surge current capacity of 44kA, and a voltage range of 1900V to 3000V. This makes the DKT3500 19-30 ideal for high-power applications that require efficient energy conversion and superior surge protection.
