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.
