Christian Lenzhofer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8901647
    Abstract: A semiconductor device includes a first semiconductor element including a first pn junction between a first terminal and a second terminal. The semiconductor device further includes a semiconductor element including a second pn junction between a third terminal and a fourth terminal. The semiconductor element further includes a semiconductor body including the first semiconductor element and the second semiconductor element monolithically integrated. The first and third terminals are electrically coupled to a first device terminal. The second and fourth terminals are electrically coupled to a second device terminal. A temperature coefficient ?1 of a breakdown voltage Vbr1 of the first pn junction and a temperature coefficient ?2 of a breakdown voltage Vbr2 of the second pn junction have a same algebraic sign and satisfy 0.6×?1<?2<1.1×?1 at T=300 K, wherein Vbr2<Vbr1.
