Abstract
A surface-mount semiconductor package comprises a semiconductor which is embedded within a plastic material body. Electrical control connections to the semiconductor package include first and second pads which are spaced apart from each other, making it easier to couple the devices in parallel. Power output is provided by metal pads. The pads may be partially sheared, to step them, thereby allowing a single thickness lead frame to be used in the manufacture of the device. On the lower face of the body there are channels which increase the electrical tracking distance and allow improved washing of residues after the device has been secured to a substrate.
