Abstract
In a semiconductor switch with a monolithically integrated field effect transistor, the source or emitter region of the field effect transistor is connected via a semiconductor region and an n-doped contact region to a first electrical terminal. In the semiconductor region, a semiconductor structure with n-doped channels is formed between the n-doped contact region and the source or emitter region of the field effect transistor; the n-doped channels electrically connect the n-doped contact region with the source or emitter region of the field effect transistor and run between p-doped regions that are connected to the n-doped contact region. The semiconductor switch is suitable as a self-switching load disconnector and has low losses in the switched-on state.
