    Abstract: A semiconductor device package includes an electrically conductive die pad having a die attach surface and an outer surface. A semiconductor die is mounted on the die attach surface. An encapsulant material encapsulates the semiconductor die and exposes the outer surface of the die pad. A first lead directly contacts the die pad, extends away from a first sidewall of the encapsulant material, and bends towards a lower side of the encapsulant material. A second lead is electrically connected to a terminal of the semiconductor die, extends away from a second sidewall of the encapsulant material, and bends towards the lower side of the encapsulant material. A first lateral section of the first lead that intersects the first sidewall is vertically offset from a second lateral section of the second lead that intersects the second sidewall.
