  • Bypass thyristor device with gas expansion cavity within a contact plate
    Patent number: 11139219
    Abstract: A bypass thyristor device includes a semiconductor device providing a thyristor with a cathode electrode on a cathode side, a gate electrode on the cathode side surrounded by the cathode electrode and an anode electrode on an anode side; an electrically conducting cover element arranged on the cathode side and in electrical contact with the cathode electrode on a contact side; and a gate contact element electrically connected to the gate electrode and arranged in a gate contact opening in the contact side of the cover element; wherein the cover element has a gas expansion volume in the contact side facing the cathode side, which gas expansion volume is interconnected with the gate contact opening for gas exchange.
