Abstract
Described is an integrated semiconductor structure for the protection from electrical discharges of electrostatic origin of particularly sensitive components of an integrated circuit. The structure is almost entirely formed directly underneath a particular input pad thus requiring a minimum useful area and is characterized by very high damaging voltage and speed of intervention because of the extremely low series resistance of the two zener junctions constituting the structure.
