<P>PROBLEM TO BE SOLVED: To provide a MOSFET capable of significantly reducing an external resistance portion. <P>SOLUTION: The MOSFET 1 is provided with a semiconductor pellet 10, gate and source inner leads 35, 36 that electrically lead out MOSFET elements to the outside, outer leads 37, 38 that are connected to respective inner leads, a header 28 that enhances radiation performance, and a resin sealant 29 that partially seals the semiconductor pellet, an inner lead group, and the header, wherein the inner leads 35, 36 are mechanically and electrically connected to the semiconductor pellet 10 with connection sections 25, 26 formed of bumps, the header 28 exposed from the resin sealant 29 is connected to an opposite side of the semiconductor pellet 10 with a drain connection section 27, and the outer leads 37, 38 are bent in a gull-wing shape. The surface mounting of the outer leads of gull-wing wing shape and the header on the backside of the resin sealant to a mounting substrate reduces the external resistance portion and improve the radiation performance. <P>COPYRIGHT: (C)2009,JPO&INPIT |
