The disclosure relates to an electronic module comprising a source terminal for receiving an input current from an electrical voltage source and comprising an electrical input capacitance which is effective with respect to the source terminal, wherein the input capacitance is connected to the source terminal via a transistor circuit. The disclosure additionally provides that the transistor circuit is configured to conduct the input current via a respective switching path of at least one transistor, and a control device is configured to switch, during the switch-on process for limiting the input current, a control voltage at a respective control terminal of the at least one transistor, in a plurality of steps, from an off value at which each switching path is switched off, to a connection value at which a contact resistance of each switching path is minimized.
