Abstract
A failure detector associated with a four-layer semiconductor protection component has a middle layer that corresponds to a low-doped semiconductor substrate of a first conductivity type. The component includes in this substrate, in addition to plurality of regions providing its protection function, at least one additional region of the second conductivity type connected to a test terminal.
