Abstract: A semiconductor component comprising at least one lateral bipolar power transistor which is composed of at least one group of single transistors with a common collector-, base- and emitter zone, which are parallel connected by three conductor track systems which bring together the emitter-, base- and collector currents of each of the single transistors; and each single transistor comprises an emitter region having an emitter-contact zone with an emitter contact, at least one active emitter zone and a connection zone between the contact zone and the active zone, a base region having a base-contact zone with a base contact and an internal base series resistor, and a collector region, said internal base series resistor being a structured semiconductor region comprising at least two ring segments, which is connected to the base contact zone and to the base contact.

Abstract: In an arrangement for coupling out an output current from a load current by a load (2), particularly a deflection coil of a cathode ray tube by means of an output resistor (4), which arrangement comprises an output current mirror (9, 10, 11), in which a control value in the form of the difference between two voltages dropping across two resistors (35, 36) for controlling the load current is generated and in which a reference current bank (12) is provided with a current mirror circuit whose input receives a constant current for generating constant currents, a minimal temperature dependence is obtained in that the output current is coupled to the emitter of at least a first output transistor (10) and at least a second output transistor (11) of the output current mirror, in that the reference current bank (12) supplies a first reference current which, together with the output current, is coupled to the emitter of the first output transistor (10) and the second output transistor (11) of the output current mirror,
