Abstract
A switching device for switching a current between a first terminal (1) and a second terminal (2) comprises a cascode circuit having a series connection of a first semiconductor switch (M) and a second semiconductor switch (J), wherein the two semiconductor switches (M, J) are connected to each other by a common point (13), and the first semiconductor switch (M) is controlled by way of a first control input in accordance with a voltage between the first control input and the first terminal (1), and the second semiconductor switch (J) is controlled by way of a second control input (4) in accordance with a voltage between the second control input (4) and the common point (13). To this end, a control circuit having a specifiable capacitance (C) is connected between the second terminal (2) and at least one of the control input.
