    摘要: Disclosed is an electronic circuit. The electronic circuit includes a transistor having a control terminal to receive a drive signal, and a load path between a first and a second load terminal. A voltage protection circuit is coupled to the transistor, has a control input, is configured to assume one of an activated state and a deactivated state as an operation state dependent on a control signal received at the control input, and is configured to limit a voltage between the load terminals or between one of the load terminals and the control terminal. A control circuit is coupled to the control input of the voltage protection circuit and is configured to deactivate the voltage protection circuit dependent on at least one operation parameter of the transistor and when a voltage across the load path or a load current through the load path is other than zero.

    摘要: A drift layer of a super junction semiconductor device includes first portions of a first conductivity type and second portions of a second conductivity type opposite to the first conductivity type. The first and second portions are formed both in a cell area and in an edge area surrounding the cell area, wherein an on-state or forward current through the drift layer flows through the first portions in the cell area. At least one of the first and second portions other than the first portions in the cell area includes an auxiliary structure or contains auxiliary impurities to locally reduce the avalanche rate. Locally reducing the avalanche rate increases the total voltage blocking capability of the super junction semiconductor device.

    摘要: A semiconductor device includes a first trench and a second trench extending into a semiconductor body from a surface. A body region of a first conductivity type adjoins a first sidewall of the first trench and a first sidewall of the second trench, the body region including a channel portion adjoining to a source structure and being configured to be controlled in its conductivity by a gate structure. The channel portion is formed at the first sidewall of the second trench and is not formed at the first sidewall of the first trench. An electrically floating semiconductor zone of the first conductivity type adjoins the first trench and has a bottom side located deeper within the semiconductor body than the bottom side of the body region.
