<p>A thyristor comprises a semiconductor element which has a control electrode and an arrangement which amplifies the control current and possesses an auxiliary emitter electrode. A housing encloses the semiconductor element and a control line, by means of which the control electrode is electrically connected to a conduit arranged in a housing wall, is included. A second control line is electrically connected to the auxiliary emitter electrode and to a conduit arranged in the housing wall. The housing is disc-shaped and comprises metal plates and an insulating ring and has a slot which is arranged in one of the metal plates and opens into a recess located opposite the control electrode and the auxiliary emitter electrode. The control line is positioned in the slot and has one end pressed against the control electrode under a spring bias action. The conduit is contained in the insulating ring and the second control line is also located in the slot in one of the metal plates. The second control line likewise opens into the recess and has its one end pressed against the auxiliary emitter electrode.</p> |
