Abstract
A protective circuit arranged on a Printed Circuit Board (PCB) has two conductor loops. At least one supply voltage track, at least one semiconductor switch and at least one control component are arranged on the PCB. A first terminal of the control component and a first terminal of the semiconductor switch are connected electrically. A first conductor loop of the protective circuit is arranged on the PCB so that it surrounds an electrically conducting connection between the supply voltage track and the semiconductor switch and/or the control component. A second conductor loop is arranged on the PCB so that it surrounds the electrically conducting connection between the first terminal of the control component and the first terminal of the semiconductor switch, and thereby screens the same from the semiconductor switch and at least from those regions of the control component that are also connected to the supply voltage track.
