Abstract
A switching arrangement for an RF-GTO is specified. It comprises a latching-type semiconductor component (GTO) of familiar construction. The circuit for turning off the semiconductor component (GTO) is designed in such a manner that the turn-off gain I.sub.A /I.sub.G, peak is distinctly less than 3 and, in particular, less than or equal to 1. During the turning-off, the drive is hard, that is to say has a high rate of increase dI.sub.G /dt and high current. A capacitance (C.sub.p) is connected directly in parallel with the semiconductor component (GTO).
