A leadframe includes leads or lead terminals, a plurality of folded features including i) support features positioned within an area defined in at least one dimension by the leads or the lead terminals configured for supporting at least one of a die pad and a first pad and a second pad spaced apart from one another, or ii) current carrying features. At least one of the folded features includes a planar portion and a folded edge structure that curves upwards at an angle of at least 45° relative to the planar portion. The folded features are configured to provide an effective increase in thickness to reduce the deformation observed in assembly.
