Abstract

A half-bridge module having two switching units, each of which includes multiple transistors connected in parallel and/or in series, in particular IGBTs or MOSFETs. The transistors are arranged on a first substrate. The half-bridge module has a temperature sensor matrix having a plurality of temperature sensors, and the temperature sensors are thermally connected to the transistors at least in some regions. A temperature sensor matrix is also provided.
