Abstract

A switching device includes a low voltage normally-off transistor and a control circuit built into a common die. The device includes source, gate and drain electrodes for the transistor and one or more auxiliary electrodes. The drain electrode is on one surface of a die on which the transistor is formed, while each of the remaining electrodes is located on an opposite surface. The one or more auxiliary electrodes provide electrical contact to the control circuit, which is electrically connected to one or more of the other electrodes.
