General information

SKKT series thyristor modules

Modules SKKT Semikron are monolithic design with dual topology of semiconductor thyristors (thyristor-thyristor type). Used in DC and AC circuits with loads to 570A and reverse pulse voltages up to 2200V.

SEMIPACK family has three different internal constructions:

Soldered construction (SEMIPACK 1) – the contact is established by solder layers;
Bonded construction (SEMIPACK 2, 3) – the connection between top electrode of the chips and DBCs is realized by bond wires;
Pressure contact construction (SEMIPACK 3, 5) – the contact is established by pressure, solder free assembly.

SKKT thyristor modules are used in various power equipment - power and control units, power regulators, AC regulators, converters, controllers of blast furnaces or chemical processes, welding equipment, and as rectifiers for AC converters.
