Abstract
In a metal-ceramic housing for a high-power GTO, a space-saving auxiliary cathode connection (5a) capable of carrying current is achieved in that it is constructed by embedding in the insulating ring (4) of the housing and is connected directly to the cathode contact plate (9) via its own connecting elements (11, 13, 15).
