A semiconductor device has a trench junction barrier Schottky diode that includes an integrated substrate p-n diode (TJBS-Sub-PN) as a clamping element, the trench junction barrier Schottky diode being suited, e.g., as a Zener diode having a breakdown voltage of approximately 20 V, for use in motor-vehicle generator systems. In this context, the TJBS-Sub-PN is made up of a combination of a Schottky diode, an epitaxial p-n diode and a substrate p-n diode, and the breakdown voltage of the substrate p-n diode (BV_pn) is less than the breakdown voltage of the Schottky diode (BV_schottky) and the breakdown voltage of the epitaxial p-n diode (BV_epi). |
