ABSTRACT:
A semiconductor diode has three adjacent regions. The doped regions are doped in the same manner and are separated from one another by a third, intrinsic region. The intrinsic region is dimensioned such that upon application of a specific external voltage at the operating temperature of the diode, it is possible for charge carriers to tunnel from one doped region to the other doped region through the intrinsic region. The semiconductor diode has a planar structure on a semiconductor substrate. A semconductor diode of this kind is suitable for use as a protective diode for other components, particularly when they are mounted on substrates consisting fo connecting semiconductors.
