  • Power transistor array temperature control system
    Patent number: 6806772
    Abstract: A method and apparatus for use with a transistor array for enhancing the array's performance and/or reliability and/or longevity by sensing the temperature of each transistor in the array and initiating corrective action to maintain its temperature within a desired operating range. Each array transistor has a temperature sensor closely thermally coupled thereto preferably mounted within the transistor package, in close physical proximity to the transistor junction.
    Type: Grant
