  • Substrate subassembly for a transistor switch module
    Patent number: 5539254
    Abstract: A substrate subassembly for a high power module, and methods involving the same. The substrate subassembly contains only one switching transistor and has at least one integral short terminal lead tab. The substrate subassemblies can be pretested at significant operating current, to obtain enhanced characterization and matching of mounted switching transistors. Trimmable gate lead resistances can be incorporated in the substrate subassemblies. Enhanced compositional, geometrical and electrical module symmetry is available. New module structures and method are afforded.
    Type: Grant
    Filed: March 9, 1994
    Date of Patent: July 23, 1996
    Assignee: Delco Electronics Corp.

  • Coplanar linear dual switch module
    Patent number: 5523620
    Abstract: A readily manufacturable low inductance linear semiconductor switching module having coplanar contacts. Also disclosed is a pretestable terminal subassembly for such a module, and a method of making such a terminal subassembly. The module can contain high power, high frequency semiconductor switching devices, operating at high power but low inductance. The module incorporates compositional, geometrical and electrical symmetry in a linear configuration. The terminal subassembly is readily fabricated and assembled into the module. In addition, it permits use of short internal leads that are readily connected to the terminal subassembly.

  • Triaxial double switch module
    Patent number: 5512790
    Abstract: A low inductance triaxial semiconductor switching module. The module permits high power semiconductor switching devices to operated at high frequency but with low inductance. The module incorporates compositional, geometrical and electrical symmetry in connection with a triaxial terminal subassembly having coplanar contact areas. The terminal subassembly is readily fabricated and assembled into the module. The module also includes short internal leads, a special circumferential array of substrates subassemblies, and a circular circuit board having gate and Kelvin circuit patterns.
