In a gate unit (47) for a hard-driven GTO (10), at least some of the electronic components (37, . . , 42) needed for driving are arranged on a printed circuit board (34). The printed circuit board (34) encloses the GTO (10), in order to achieve low-inductance contact, in a plane lying between the anode side and the cathode side of the GTO (10) parallel to the semiconductor substrate (17) of the GTO (10) and is directly connected to the cathode contact (14) and the gate connection (22) of the GTO (10). A compact structure with, at the same time, improved mechanical stability is achieved in such a gate unit in that the components (37, . . , 42) are arranged on the printed circuit board (34) around the GTO (10), in the immediate vicinity of the GTO (10).
