Our large selection of power semiconductors

Power semiconductors are essential components of power electronics. They are responsible for controlling and switching high electrical currents and voltages. Therefore, they consist of conventional semiconductor devices that have been specially upgraded to operate smoothly in high current and voltage ranges. Normal semiconductor components would be damaged or even destroyed if the amperes and voltages were too high. Power semiconductors are used in transportation technology, in industry, in mechanical engineering and basically in HVDC (high voltage direct current) transmission. They are also used in all those areas where the transformation or adaptation of voltage, current or frequencies is necessary. Depending on the application, Bürklin Elektronik has a large selection of individual power semiconductor models.
