Abstract
A first embodiment is a common drain+clip. It has a conventional drain contact on its bottom surface and is flip chip mounted on a half-etched leadframewhich has external source, gate and drain contacts connected to the sources, gate and common drain of the die. Common drain clipconnects the drainto external contacts between opposite gate contacts. A second embodiment is a direct drain embodiment+heatslug. The devicehas a top drain contactthat extends to the common drainacross the bottom of the die which is flip chip mounted to a half-etched leadframe having external source, gate and drain contacts connected to the sources, gates and common drain of the die
