Abstract
A transistor device is disclosed. The transistor device includes: a semiconductor body; a source conductor on top of the semiconductor body; a source clip on top of the source conductor and electrically connected to the source conductor; a first active device region arranged in the semiconductor body, covered by the source conductor and the source clip, and including at least one device cell; and a second active device region arranged in the semiconductor body, covered by regions of the source conductor that are not covered by the source clip, and including at least one device cell. The first active device region has a first area specific on-resistance and the second active device region has a second area specific on-resistance, the second area specific on-resistance being greater than the first area specific on-resistance.
