    • A light fired thyristor including a semiconductor body having four zones of alternatingly opposite conductivity types constituting a first or cathode emitter zone, a control base zone adjacent thereto, a main base zone and a second or anode emitter zone with the cathode emitter zone being formed within the control base zone at one major surface of the semiconductor body and being divided into a plurality of separate regions of which one serves as the firing region of the first emitter zone to fire the thyristor in response to impinging radiation energy. The firing region of the first emitter zone is provided in part with a first ohmic contact which is ohmically connected to a further ohmic contact connected to the control base region adjacent the edge of the semiconductor body. The remaining regions of the first emitter zone are provided with a cathode contact which simultaneously contacts the portions of the control base zone between these regions and forms short circuits with the control base zone. Consequently with interfering currents which are approximately uniformly distributed over the thyristor area, an increase in potential is produced in the firing region of the first emitter zone which increase is in the same direction as the increase in potential in the firing region of the control base zone and the likelihood of a faulty firing of the thyristor is reduced.
    • 一种点燃晶闸管,包括具有构成第一或阴极发射区的交替相反导电类型的四个区域的半导体本体,与其相邻的控制基区,主基极区和具有阴极发射区的第二或阳极发射区, 所述控制基区在所述半导体主体的一个主表面处,并且被分成多个分开的区域,其中一个区域用作所述第一发射区的点火区域,以响应于入射辐射能而触发所述晶闸管。 第一发射区的发射区域部分地设置有第一欧姆接触,欧姆接触与连接到与半导体本体的边缘相邻的控制基极区域的另一欧姆接触欧姆连接。 第一发射区的剩余区域设置有阴极接触件,其同时接触这些区域之间的控制基区的部分并且与控制基区形成短路。 因此,由于大致均匀地分布在晶闸管区域上的干扰电流,在第一发射区的点火区域产生增加的电位,该增加与控制基区的烧制区域中的电位增加方向相同 并且晶闸管发生故障的可能性降低。

    • A gate turn-off thyristor comprising, a first emitter layer of one conductivity type, a main base layer of another conductivity type connected to said first emitter layer and a control base layer of the first conductivity type connected to the main base layer. A second emitter of the other conductivity type is connected to the control base layer at a junction which surrounds a portion of the second emitter layer. An emitter contact is connected to the second emitter layer and a control base contact is connected to the control base layer. The gate turn-off thyristor is turned off by a short circuiting of the control base contact with the emitter contact. The surface resistance of the control base layer between the second emitter layer and the control base contact is selected so that, with a control base turn-off current applied which is sufficient for turning off the thyristor, a potential appears on a lateral resistance in the control base layer which is less than a potential appearing at the junction. This difference in potential is used as an additional driving potential for the hole or electron current flowing over the lateral resistance and the control base layer.

    • The invention concerns a field-effect controlled semiconductor component with at least four regions of alternating opposite performance types: an anode-side emitter region, a first and a second base region connected to the emitter region, and a cathode-side emitter region; the cathode-side emitter region and the first base region from the source and drain of an MOS field effect transistor. The component also comprises an anode contact, a contact at the cathode-side emitter region and a control electrode contact of the MOS field effect transistor. The invention lies in the fact that a p+ region (36) which is adjacent to the cathode-side base region, separate, and accomodated in the anode-side n- base region (20), is connected via a separate component as a coupling element (80) with non-linear current/voltage characteristics to the cathode contact, the said region (36) being directly surrounded by the anode-side base region (20). When the field effect transistor is switched off the electrical potential in the area surrounding the supplementary p+ region (36) will exceed the threshold voltage of the coupling element, so that the supplementary p+ region (36) acts as a current sink by which the hole current can drain off against low resistance. A parasitic thyristor function is thus avoided.
