DEVICE FOR PROTECTING AGAINST OVERCURRENTS IN ELECTRIC CIRCUITS AND USES OF SAID DEVICE IN A FUSE LINK AND IN A RELATED LIMITING FUSE AS WELL AS IN FUSES FOR PROTECTING SEMICONDUCTORS
The invention provides an overcurrent protection device (1), comprising a current input terminal (2); a central terminal (3) for the output of current overshoots (I.sub.s); and a terminal (4) for the output of non impulse currents (I.sub.c) which is outwardly connected to the voltage of the central terminal (3) before the occurrence of the current overshoot (Is) at the input terminal (2); and an electrical conductor element (5) connected between the current input and output terminals (2 and 4); such conductor element showing a reduced self-induction (L) when operating without current overshoots but, which, in case that current overshoots are present at the input terminal (2), produces a high drop of the induction voltage between such input terminal and the output terminal (2 and 4); wherein the central terminal (3) is arranged in the vicinity of the current input terminal (2) at a distance (D) that may be regulated, so that when, as a result of a current overshoot, the inductive voltage drop between the input terminal and the non-impulse current output terminal (2 and 4) exceeds the dielectric strength of the dielectric material present between the input and central terminals (2 and 3), and thanks to the skin effect, an arc is generated between such input and central terminal (2 and 3), thus preventing the flow of current overshoots (Is) through the conductor element (5).

Device for protecting against overcurrents in electric circuits and uses of said device in a fuse link and in a related limiting fuse as well as in fuses for protecting semiconductors
An overcurrent protection device comprises a current input terminal; a central terminal for output of current overshoots; and a terminal for output of non-impulse currents connected to a voltage of the central terminal. An electrical conductor element is connected between the input and output terminals at a reduced self-induction when operating without current overshoots. When current overshoots are present at the input terminal, the conductor produces a high drop of induction voltage between the input and output terminals. The central terminal is arranged in the vicinity of the input terminal at a distance that may be regulated. When due to current overshoot, the inductive voltage drop between the input and the non-impulse current output terminals exceeds the dielectric strength of the material present between the input and central terminals, an arc is generated between the input and central terminals to prevent the flow of current overshoots through the conductor element.
Integrated fuse
A semiconductor wafer includes first zones containing integrated circuits, each first zone including a substrate and a sealing ring at a periphery of the substrate. The first zones are separated from each other by second zones defining cutting lines or paths. The integrated circuit includes an electrically conductive fuse that extends between a first location inside the integrated circuit and a second location situated outside the integrated circuit beyond one of the cutting lines. This electrically conductive fuse includes a portion that passes through the sealing ring and another portion that straddles the adjacent cutting line. The portion of the fuse that passes through is electrically isolated from the sealing ring and from the substrate. The straddling portion is configured to be sliced, when cutting the wafer along the cutting line, so as to cause the fuse to change from an electrical on state to an electrical off state.
