Disclosed is a power component serving to reliably switch inductive loads and having (50) a current detection element for detecting the current flowing through the inductive load. The component comprises a protection element (48) which is connected to the source terminals of the sensing element (41) and the regulating member (42). The protection element serves to protect against parasitic effects between the sensing element and the regulating member.

The invention relates to a semiconductor component, which can be produced in a simple, rapid, but nevertheless reliable manner and can be used in particular for power applications. The component comprises: a semiconductor chip (2, 12); a lower first primary electrode layer (3, 13) configured on a first side (2a) of the semiconductor chip (2, 12); a lower control electrode layer (4, 14) configured on said first side (2a); an isolation layer (5, 15), which partially covers the lower first primary electrode layer (3, 13) and is configured on the first side (2a) between the lower first primary electrode layer (3, 13) and the lower control electrode layer (4, 14); an upper first primary electrode layer (6, 16) configured on the lower first primary electrode layer (3, 13); an upper control electrode layer (7, 17), which is configured on the lower control electrode layer (4, 14) and the isolation layer (5, 15), extending over the isolation layer (5, 15) partly above the lower first primary electrode layer (3, 13); and a second primary electrode layer (9, 19) that is configured on a second side (2b) of the semiconductor chip (2, 12).

The invention relates to a diode arrangement (10) and a generator (20), using zener diodes (2-7). Said diode arrangement (10) comprises alternating voltage terminal connectors (U, V, W) and direct voltage terminal connectors (B+, B-). Said zener diodes (2-7) are used in the direction of transmission in order to rectify an alternating voltage applied to the alternating voltage terminals (U, V, W), a lower limit (8) being provided for the zener voltage of the zener diodes (2-7). Said lower limit (8) of the zener voltage is lower than a lower pre-defined direct voltage (11).

The invention relates to a method for producing an electrical connection between the electrical connections of a semiconductor component forming part of an electrical subassembly and other parts of this electrical subassembly, by means of a pressed screen which has inner terminals (11) and outer terminals (10) which are electrically connected to said inner terminals by metal strip conductors (12). According to said method, the semiconductor element and the pressed screen are brought together in such a way that at least two electrical connections of the semiconductor component are positioned on corresponding inner terminals, enabling the semiconductor component to be subsequently immovably fixed to the two inner terminals. This mechanical attachment simultaneously creates an electrical connection between the electrical connections of the semiconductor element and the inner terminals. Said metal grating is a metal grating, especially a pressed screen, that is already embedded in a non-electroconductive material (1; 9) at least in a partial area, on at least one side, before being assembled with the semiconductor component. This procedure ensures bond-free contacting of semiconductor components for high performance applications with which power losses of more than 1 Watt can occur.

The invention relates to a connector, especially for a control device (100), having a connector input with at least two input terminals (1, 2, 3), a connector output with at last two output terminals (4, 5, 6) and at least one connecting part (10, 20) by means of which matching terminals (1, 2, 3, 4, 5, 6) - input and output terminals - are connected to one another. In order to exclusively use simple connecting parts that can also be used in the realization of several connector variants, the connector input and the connector output are decoupled, wherein at least one first connecting part (10) only comprising input terminals (1, 2, 3) and at least a second connecting part (20) only comprising output terminals (4, 5, 6) are provided. Both connecting parts (10, 20) are placed one on top of the other in such a way that the matching terminals superimpose in at least one crossing point. The matching terminals are connected to one another by contacting (7).
