摘要：
A transistor component is suited for controlling large currents, even given high frequencies. The transistor component includes integrated emitter resistors which are arranged between partial-emitter regions and emitter-metal contacts. The integrated emitter resistors cause a stabilized, uniform current distribution both over the various partial-emitter regions, and within the partial-emitter regions, and bring about an improved current carrying capacity, as well as improved high-frequency properties, particularly in view of the finite magnitude of the extrinsic base resistance.
