A charge-balance power device includes a semiconductor body having a first conductivity type. A trench gate extends in the semiconductor body from a first surface toward a second surface. A body region has a second conductivity type that is opposite the first conductivity type, and the body region faces the first surface of the semiconductor body and extends on a first side and a second side of the trench gate. Source regions having the first conductivity type extend in the body region and face the first surface of the semiconductor body. A drain terminal extends on the second surface of the semiconductor body. The device further comprises a first and a second columnar region having the second conductivity, which extend in the semiconductor body adjacent to the first and second sides of the trench gate, and the first and second columnar regions are spaced apart from the body region and from the drain terminal.
