Abstract

An electrical component having a primary winding, a first field-effect transistor, configured as a switch of the primary winding, for switching the primary winding, a quench winding for quenching the inductive load of the primary winding when switching off the primary winding, and a second field-effect transistor, configured as a switch of the quench winding, for switching the quench winding. In the process, the first field-effect transistor is operated in linear operation and the second field-effect transistor is operated in linear operation or in a clock-pulsed operation between the linear operation and a switched-off state during a switching-off process of the quench winding.
