SCR unit SKKT92-12E The company SEMIKRON, one of the world's leading manufacturers of power electronics, is a leader in power modules. Many innovative developments of SEMIKRON were introduced as the industry standard. SEMIKRON invented the world's first line of isolated power modules - SEMIPACK®. In 2008, SEMIKRON completely changed the approach to the design of these components, the construction of which was developed by this company 30 years ago. The new form reduces the number of soldered layers, uses advanced chips with the angular position of the shutter, as well as spring signal connections. These modules have: high speed (critical rate of rise of voltage dU/dt and current di/dt), the real value of the current surge in the open state (peak current) of the thyristor is up to 27 units, large area of the module basis, corresponding to the power section of the findings, low thermal resistance (high operating current), high efficient module structure. The thyristor module SKKT92/12E is a typical representative of power modules SEMIPACK. The module is designed to 1200V voltage at a rated current of 92A. The module thyristor has the thermal resistance Rth(j-c) "crystal-case" of no more than 0.2°C/W, while providing a 10% increase in the operating current. Continuous RMS current exceeds the average current IT(AV) by 2 times, which characterizes the minimal loss of power on the resistive elements of the thyristor, including power leads. Maximum critical rate of increase of the commutation voltage is at least 1000V/microsecond. The block diagram of the module is a two series-connected power thyristors. The main applications of SKKT92/12E module are: management of the DC motor, AC motor soft starter, temperature control (including chemical processes in furnaces), management of professional lighting (studios, theaters), etc.
