摘要： The temperature of a power semiconductor component is monitored by feeding the block current of a bipolar transistor which is in thermal contact with the component to an amplifying current mirror. The output signal of the current mirror is compared with a reference current. If the mirrored current is greater than the reference current, then the system produces a corresponding output. Temperatures of the power semiconductor component below 140.degree. C. can be reliably detected.

摘要： In order to supply a load, e.g. an electric motor, with current bidirectionally, an H bridge configuration containing four switching transistors is used. In order to attain outstanding electrical conductivity and also thermal conductivity, a half-bridge configuration containing two transistors of opposite conductivity types is constructed. Each of the transistors is realized on a chip, the rear sides of which chips are seated on a common conductive support preferably produced from metal. Each housing is equipped with a support of this type. The rear side of each of the two chips is formed from a drain or source electrode of the transistors. A load can be connected to the support. Two half-bridge configurations can advantageously be combined to form an H bridge configuration.

摘要： MOSFET and IGBT components protected against overvoltage by a limiting diode inserted between drain or, respectively, collector terminal and gate terminal are provided. A freewheeling diode connected to the component having a limiting diode with a breakdown voltage that is lower than the breakdown voltage of the freewheeling diode by a defined amount is provided. This over-voltage protection can be achieved in a simple way by integrating the limiting diode into the semiconductor body of the freewheeling diode and by a corresponding arrangement of the anode zone of the limiting diode.
