ABSTRACT:
A power semiconductor package, including a leadframe having at least one first terminal, a second terminal and a third terminal. The package also includes a semiconductor power die having a bottom surface defining a first current carrying electrode and a top surface on which a first metalized region defining a second current carrying electrode and a second metalized region defining a control electrode are disposed, the bottom surface being coupled to the leadframe such that the first terminal is electrically connected to the first current carrying electrode. A clip is also coupled to the first metalized region defining the second current carrying electrode and to the second terminal such that it is electrically coupled to the second current carrying electrode.
