Abstract

A semiconductor device includes a gate pad, a first source pad and a second source pad insulated from each other, a drain pad, a main region, and a sense region for detecting a forward current and a reverse current. The main region and the sense region each include a plurality of unit cells which are in parallel connection, the number of unit cells in the sense region being smaller than the number of unit cells in the main region. A source electrode of any unit cell in the main region is connected to the first source pad, and a source electrode of any unit cell in the sense region is connected to the second source pad.
