ABSTRACT:
A voltage protection arrangement (10) comprises a semiconductor substrate (12) having at least two electrical conductors (16,18,20) adjacent an edge of the substrate. An aperture (22) extends from the edge towards a point between the two electrical conductors. The aperture (22) reduces conductance between the two electrical conductors (16,18) in a region adjacent the edge of the substrate (12), such that if an excess voltage occurs between the two conductors (16,18), a reduced current flows in the region.
