  • Patent number: 6776663
    Abstract: An electronic component has a housing and at least two terminal pins protruding out from a first side face of the housing. The housing has an isolation barrier formed between the at least two terminal pins. The isolation barrier extends the leakage path between two neighboring terminal pins and consequently increases the dielectric strength.

  • Patent number: 6323531
    Abstract: The invention relates to a two-chip power IC, in which a sensor chip having a sensor is mounted on a switch chip having a switch. The sensor is electrically connected to the switch in order to turn the switch off when a temperature detected by the sensor exceeds a threshold value which can be preset. In order to ensure that the sensor chip is heated more quickly, at least one supply line for the switch is routed in the vicinity of the sensor so as to assure good heat transfer from the supply line to the sensor.
