Abstract
A semiconductor device includes a transistor array and a sense pad. The transistor array includes a plurality of transistor cells electrically connected in parallel between a source electrode and a drain structure. The drain structure is formed in a semiconductor portion based on a single-crystalline wide bandgap material. A sense element formed from the wide bandgap material includes at least one rectifying junction electrically connected between the sense pad and the source electrode.
