The power switch has considerably reduced common-mode interference and relatively reduced circuit complexity. The power switch is formed of a semiconductor chip on a leadframe. A first terminal of the semiconductor chip is connected to the active potential and a second terminal for inactive potential is connected to the leadframe. The second terminal is either the drain of a transistor or the anode of a diode.

EMC-optimized power switch

The invention relates to a switching transistor presenting reduced switching losses. In the switching transistor, output capacitance is very high when drain/source voltages are low. As the drain/source voltage increases, the capacitance falls to such low values that the energy stored in the transistor becomes very low.
