Abstract

A power semiconductor module for energy distribution, includes at least one power semiconductor, connection terminals for connecting the power semiconductor module, and a housing, in which protection from explosion is ensured in the module even in the event of electric arcs. Therefore, each power semiconductor and each connection terminal is disposed in the housing, and the housing includes an exhaust gas channel for the controlled withdrawal of hot gases and/or plasma in the event of an explosion.
