Abstract
In this protective arrangement, a resistor between a pad (p) and a transistor to be protected is implemented with an expansion region (e) which lies completely below the pad (p) and extends beyond the latter along the entire circumference of the pad. An elongate region (z) extends along the circumference of the expansion region (e) and is connected to circuit ground via an interconnection track (b). The connection between the elongate region (z) and the interconnection track (b) has a low resistance.
