Abstract: Various example embodiments concern an integrated circuit (IC) package having a clip with a protruding tough-shaped finger portion. The clip can be used in various IC packages including, for example, soft-soldered compact power packages such as rectifiers with specified surge current capability. Such embodiments can be implemented to allow for a visual inspection capability of the soldering area for connecting a lead frame, via the clip, to a surface of the IC package die, while still providing sufficient thermal mass to limit the temperature increase during forward surge current loads. This results in a simple to manufacture design without compromising too much on performance.
