Thyristor Discs

All discs are assembled in high reliable, robust and hermetic sealed ceramic housings in order to avoid mechanical damages as well as almost any negative environmental influences as e.g. high humidity. As an extension, our product portfolio contains disc types as light triggered thyristors (LTT). These ceramic discs offer an easy way of triggering by using laser diodes and optical fibers to avoid insulation problems between load and trigger unit. Higher reliability thanks to less electronic components on high potential by using the internal protection functions (BoD and dv/dt protection). The power range covers blocking voltages from 5200V up to 8000V and current ratings from 550A up to 4000A.
