Halbleiter-Leistungsbauelement mit Schmelzsicherung

摘要

The invention relates to a semiconductor power component (diode 18) comprising a lead (11) and a safety fuse (12) that is situated in the principal current path. Said fuse comes into action when there is thermal overstress and is especially used in the electric system of motor vehicles. The aim of the invention is to specifically switch off the endangered component when the semiconductor power components are overstressed, for preventing sequential damages, whereby switching-off is predetermined. A partial section (11b) of the lead (11) and/or the points of contact thereof in the principal current path of the semiconductor is/are designed as a safety fuse (12) which comes into action when there is a predetermined, current-dependent temperature value.
