  • Power semiconductor component for voltage limiting, arrangement having two power semiconductor components, and a method for voltage limiting
    Patent number: 11973147
    Abstract: A power semiconductor component for voltage limiting includes a rear-side base zone electrically contacted with a rear-side electrode and a front-side base zone electrically contacted with a front-side electrode. At least one switch-on structure is embedded at least into one of the rear-side base zone and the front-side base zone and is electrically contacted by the electrode contacting the embedding base zone. At least one triggering structure is provided as a breakdown structure of a first type, present between the front-side and rear-side electrodes. At least one further triggering structure is provided as a breakdown structure of a second type, present between the front-side and rear-side electrodes. The front-side and rear-side electrodes are each electrically conductively pressure-contacted by an electrically conductive contact plate at least one of which functions as a heat sink for dissipating heat generated in the semiconductor body.

  • Crankcase ventilation device
    Patent number: 9238980
    Abstract: A vehicle may include an internal combustion engine having a crankcase and a crankcase ventilation device. The crankcase ventilation device may have at least one oil separating device and an oil return that feeds separated oil back to the crankcase. The vehicle may include a conveying device for driving a fluid other than blow-by gas. The conveying device may also drive the blow-by gas in the crankcase ventilation device.
