A packaged power transistor device (100) having a leadframe including a flat plate (110) and a coplanar flat strip (120) spaced from the plate, the plate having a first thickness (110a) and the strip having a second thickness (120a) smaller than the first thickness, the plate and the strip having terminals (212; 121a). A field-effect power transistor chip (210) having a third thickness (210a), a first and a second contact pad on one chip side, and a third contact pad (211) on the opposite chip side, the first pad being attached to the plate, the second pad being attached to the strip, and the third pad being coplanar with the terminals. Encapsulation compound (130) filling the thickness difference between plate and strip, and spaces between chip and terminals, wherein the compound has a surface (101) coplanar with the plate surface (111) and the opposite surface (102) coplanar with the third pad (211) and the terminals (212; 212a), the distance (104) between the surfaces being equal to the sum of the first (110a) and third (210a) thicknesses.
