  • Publication number: 20240105837
    Abstract: A power semiconductor device is proposed. The power semiconductor device includes a semiconductor body and a wiring area over a first surface of the semiconductor body. The power semiconductor device further includes a bipolar power semiconductor element including a first load electrode in the wiring area, an active area in the semiconductor body, and a second load electrode at a second surface of the semiconductor body. The power semiconductor device further includes a current sensing element including a pn or pin junction. The power semiconductor device further includes an optical window configured to allow electromagnetic radiation caused by an on-current of the bipolar power semiconductor element to pass to the current sensing element.

  • Publication number: 20170174712
    Abstract: A silicon-containing azodicarboxamide is obtainable by reacting an azodicarboxy compound with an aminosilane. The silicon-containing azodicarboxamides are suitable for use in cable sheathing, hoses, drive belts, conveyor belts, roll coverings, footwear soles, ring seals and damping elements.

  • Patent number: 9108992
    Abstract: The invention relates to a composition of a carboxyl-functionalized silicon-containing precursor compound of at least two different organic acids, said composition having two, three, or four carboxyl groups functionalized with various hydrocarbon groups according to formula I and/or II. Said carboxyl groups can be released as carboxylic acids and can be used as silane hydrolysis catalysts and/or silane condensation catalysts. The invention further relates to methods for producing the composition, to the use of the composition for cross-linking polymers, and to a formulation of the composition in the form of a masterbatch.
