Patent ID: 7466016

Claim:
A conductive lead frame for supporting a semiconductor device encapsulated in a molded housing, the lead frame comprising: a metal backing tab which supports the semiconductor device and has an extending portion extending from an edge thereof that extends beyond a boundary of the molded housing; and a top leg, a middle leg and a bottom leg; wherein the top leg, the middle leg and the bottom leg are all coupled to the semiconductor device each having a lead terminal portion extending beyond the boundary of said molded housing, wherein each of the three legs protrude from the molded housing, wherein the top leg has a first top leg section that protrudes directly away from the molded housing, and a second top leg section that bends toward a direction of a face of the molded housing, and a third top leg section bending downward, wherein the middle leg has a first middle leg section connected to the package that protrudes away from the molded housing, and a middle leg downward section that points downward, wherein the bottom leg has a first bottom leg section that protrudes away from the molded housing face, and a second bottom leg section that points away from the molded housing face, and third bottom leg section that points downward, wherein the metal backing tab is effective to function as a heatsink and extends outside the boundary of the molded housing.
