Abstract
A semiconductor device includes a semiconductor body having opposite first and second surfaces. The semiconductor body includes a load current component having a load current transistor area and a sensor component having a sensor transistor area. The load current transistor area and the sensor transistor area share a same transistor unit construction. The load current transistor area includes first and second transistor area parts, and the sensor transistor area includes a third transistor area part. The first and the third transistor area parts differ from the second transistor area part between the first and the third transistor area parts by a load current transistor area element being absent in the second transistor area part. The second transistor area part is electrically disconnected from a parallel connection of the first and second transistor area parts by the load current transistor area element being absent in the second transistor area part.
