Abstract (en)

[origin: DE19806817C1] The power switch includes a semiconductor chip (3) on a lead frame (2). The chip (3) has at least a first terminal (D,K) for an active potential and a second terminal (S,A) for a quiescent potential. The lead frame (2) is connected to the second terminal (S,A). Preferably the first terminal is the drain and the second terminal is the source of a transistor (6). Alternatively the first terminal is the cathode and the second terminal is the anode of a diode. The chip may be mounted over the source(s) of the transistor on the lead frame (2). A control terminal (G) of the transistor (6) may be connected via trenches in the chip (3) to the free surface of the chip.
