Patent ID: 7687826

Claim:
A thyristor system comprising: a main thyristor having a semiconductor body in which a p-doped emitter, an n-doped base, a p-doped base and an n-doped emitter are arranged successively proceeding from a rear side, and which has a triggering stage region having at least one triggering stage and a main cathode region adjacent to the triggering stage region in the lateral direction, a drive thyristor having a semiconductor body, in which a p-doped emitter, an n-doped base, a p-doped base and an n-doped emitter are arranged successively proceeding from a rear side and which has a triggering stage region having at least one triggering stage and a main cathode region adjacent to the triggering stage region in the lateral direction, the semiconductor body of the drive thyristor being distinct from the semiconductor body of the main thyristor, the n-doped emitter of the drive thyristor being electrically connected to a control terminal of the main thyristor, the p-doped emitter of the drive thyristor being electrically connected to the p-doped emitter of the main thyristor, and the drive thyristor having a measure for recovery protection and/or a breakdown structure.
