A stacked III-V semiconductor component having a stack with a top, a bottom, a side surface, and a longitudinal axis. The stack has a p+ region, an n− layer, and an n+ region. The p+ region, the n− layer, and the n+ region follow one another in the specified order along the longitudinal axis and are monolithic in design, and include a GaAs compound. The n+ region or the p+ region is a substrate layer. The stack has, in the region of the side surface, a first and a second peripheral, shoulder-like edge. The first edge is composed of the substrate layer; the second edge is composed of the n− layer or of an intermediate layer adjacent to the n− layer and to the p+ region and the first and the second peripheral edges each have a width of at least 10 μm.
