Abstract
A main thyristor () has a recovery protection which is integrated into a drive thyristor () whose n-doped emitter () is electrically connected to a main thyristor control terminal (). Moreover, the p-doped emitter () of the drive thyristor () is electrically connected to the p-doped emitter () of the main thyristor (). Various optional measures for realizing a recovery protection are provided in this case. A method for producing a thyristor system having a main thyristor and a drive thyristor, the drive thyristor () having anode short circuits () involves introducing particles () into a target region () of the semiconductor body () of the drive thyristor (), the distance between the target region () and a front side () of the semiconductor body () opposite to the rear side () being less than or equal to the distance between the p-doped emitter () and the front side ().
