    摘要: A main thyristor (1) has a recovery protection which is integrated into a drive thyristor (2) whose n-doped emitter (25) is electrically connected to a main thyristor control terminal (140). Moreover, the p-doped emitter (28) of the drive thyristor (2) is electrically connected to the p-doped emitter (18) of the main thyristor (1). 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 (2) having anode short circuits (211) involves introducing particles (230) into a target region (225) of the semiconductor body (200) of the drive thyristor (2), the distance between the target region (225) and a front side (201) of the semiconductor body (200) opposite to the rear side (202) being less than or equal to the distance between the p-doped emitter (28) and the front side (201).

    摘要: A thyristor comprises a semiconductor body with a front and back face, an edge, a first semiconductor zone, embodied in the region of the rear face and a second semiconductor zone, adjacent to the first semiconductor zone, whereby the edge has a bevelled embodiment in the region of the transition between the first and second semiconductor zones, at least one third semiconductor zone, arranged in the region of the front face of the semiconductor body and at least one fourth semiconductor zone, arranged between the at least one third semiconductor zone and the second semiconductor zone. The fourth semiconductor zone terminates before the edge in the lateral direction of the semiconductor body, in order to reduce the amplification of a parasitic bipolar transistor formed in the region of the edge by the fourth semiconductor zone, the second semiconductor zone and the first semiconductor zone.
