    摘要: The temperature of a power semiconductor component is monitored by feeding the block current of a bipolar transistor which is in thermal contact with the component to an amplifying current mirror. The output signal of the current mirror is compared with a reference current. If the mirrored current is greater than the reference current, then the system produces a corresponding output. Temperatures of the power semiconductor component below 140.degree. C. can be reliably detected.

    摘要: A thyristor is controlled by a phototransistor whose photo current is reduced by a MOSFET if the thyristor voltage surpasses a prescribed value. The MOSFET is controlled by two current supplies. The first current supply is connected between a gate terminal and a connecting terminal of the thyristor. The second current supply is connected between the gate and source of the MOSFET. The maximum current capacity of the first current supply is greater than the maximum current capacity of the second current supply.

A second switch is controllable by an input signal and has first and second load terminals. A line is connected to a fixed potential and to the first load terminal of the second switch. The second load terminal of the second switch is switched from a first to a second potential as a function of the input signal. The first and second potentials are between potentials of the first and second terminals of the voltage source. The first and second potentials are applied to the control input of the first switch for making the first switch conducting whenever an input signal is applied.

    摘要: A semiconductor element has a semiconductor body of a first conductivity type. The semiconductor body has a zone of a second conductivity type embedded. Further regions of the second conductivity type surround the zone of the second conductivity type like a well. The further regions are interrupted in at least one location by a channel that is formed by the semiconductor body. The further regions are doped with a doping concentration that is high enough so that the further regions are not completely depleted of charge carriers when the semiconductor element is revere-biased.

    摘要: A junction field-effect transistor containing a semiconductor region with an inner region is described. In addition, a first and a second connecting region, respectively, are disposed within the semiconductor region. The first connecting region has the same conductivity type as the inner region, but in a higher doping concentration. The second connecting region has the opposite conductivity type to that of the inner region. This reduces the forward resistance while at the same time maintaining a high reverse voltage strength.
