摘要

Power semiconductor module (2; 2a) with a detector (12; 12b; 12c; 12e) for detecting a by means of a power semi-conductor component flowing in the main current circuit, wherein the detector comprises:– a first and a second circuit - conductor structure (14, 15; 14b, 15b; 14c, 15c; 14e, 15e);– a bonding wire (16; 16c, 16d), which is available at a first and a second contact point (c, d) with the first and second circuit - conductor structure is connected; and– a pair of contact - conductor structures (18, 19; 18b, 19b; 18c, 19c; 18e, 19e), which streams from the vicinity of the first and second contact point of the first and second circuit - conductor structure are led out,the detector is designed for this purpose, a potential difference between the pair of contact - conductor structures to be detected, the fact that a circuit main current through the first circuit - conductor structure, the bonding wire and then through the second circuit - conductor structure flows, in order to detect a potential difference in the bonding wire.
