Abstract

A high-voltage breakover diode is proposed, which takes on the function of an ignition voltage distributor of an internal combustion engine having solid-state highvoltage distribution. The high-voltage breakover diode comprises a cascade of breakover diode chips, a polyimide layer having recesses in the region of the cathode connection being provided between the individual breakover diode chips produced using planar technology, in each case on the top of the breakover diode chips, and the mechanical and electrical connection of the individual breakover diode chips being effected by means of a conductive adhesive (FIG. 3).

Claims9

Dependent claims

A high-voltage breakover diode comprising:

a plurality of series-connected breakover diode chips, each of the breakover diode chips having a p-n junction covered by an insulation layer, each of the p-n junctions and each of the insulation layers being disposed on a top side of a corresponding one of the breakover diode chips, the breakover diode chips being produced using planar technology;
a first electrode disposed on the top side of each of the breakover diode chips;
a first electrically conductive layer covering each of the first electrodes;
a second electrode disposed on a bottom side of each of the breakover diode chips;
a second electrically conductive layer covering each of the second electrodes;
an electrically insulating plastic layer disposed on the top side of each of the breakover diode chips, each of the electrically insulating plastic layers having a recess in a region of the first electrodes;
and
a connecting layer for electrically and mechanically coupling the breakover diode chips.
