Powersem GmbH, founded in 1985, in Schwabach, Germany, by Madan Mohan Chadda, is a company devoted 100% to the design, development and production of multiple chip semiconductor modules. Today, POWERSEM is considered as one of the world leaders in supplying isolated base packaged modules for standard, fast single, three phase, half and fully controlled power semiconductor modules including solid state relays. POWERSEM GmbH has also successfully developed strategic alliances with high tech silicon foundries, showing a total commitment to serve its customers, now and in the future. These small but thermal efficient mini circuit modules provide the ‘SINGLE PACKAGE’ concept, which can be used as single devices in series or parallel replacing SOT-227, TO-247 discretes as well as older standard dual multiple chip modules traditionally supplied by various competitors. Currents from 8 – 230 Amperes and voltages up to 1800 Volts are standard.
