    Abstract: The present invention creates an operating method for a semiconductor component having a substrate; having a conductive polysilicon strip which is applied to the substrate; having a first and a second electrical contact which are connected to the conductive polysilicon strip such that this forms an electrical resistance in between them; with the semiconductor component being operated reversibly in a current/voltage range in which it has a first differential resistance (Rdiff 1 ) up to a current limit value (It) corresponding to an upper voltage limit value (Vt) and, at current values greater than this, has a second differential resistance (Rdiff 2 ), which is less than the first differential resistance (Rdiff 1 ).

    Abstract: A circuit suitable as an ESD protective element where on occurrence of overvoltage, a low resistance non-destructive path is provided via a semiconductor resistor, which otherwise has a resistance of higher value, for example in a radio-frequency circuit (fig 5). The semiconductor component has a substrate 1, and a cuboid polysilicon strip 10 having electrical contacts 11 and 12. A controllable current source 15 provides the polysilicon strip 10 with a reversible response up to a critical upper current value, the strip having a first differential resistance R diff1 up to a current limit value I t corresponding to an upper voltage limit V 1 , and a second differential resistance R diff2 , less than R diff1 , at current levels above this (fig 2). In second embodiment (fig 4) the semiconductor strip is composed of separate strips of polysilicon (fig 4: 10a-d) having different dopings and lengths.
