The wide portfolio consists of standard thyristors and diodes with epoxy disc case, high power thyristors and diodes with ceramic disc case. Bipolar Power Semiconductors are applied in the most varied fields of application in a power range of just a few kilowatts up to several gig watts. The light triggerable thyristors (LTT´s) are very compact in size and especially fast in reaction. Hence without high power thyristors high voltage DC couplers would not be reality today, when two grids can not be coupled by AC links.
