SEMICONDUCTOR DEVICE FOR POWER

摘要

The purpose of the present invention is to obtain a compact and high-reliability semiconductor device for power in which the holding power between a press-fit terminal and a connector is increased. This semiconductor device (1) for power is provided with: a plurality of lead patterns (23, 24, 25) having one end side connected to one of circuit members that includes a semiconductor element (8) for power and having through-holes at predetermined positions on the other end side; a sealing body (4) formed so as to seal the circuit members; female connectors (5) formed from a main surface (4f) towards a circuit surface (6f) of the sealing body (4); and press-fit terminals (2) having a connector insertion terminal secured to a female connector. The connector insertion terminals have: an anchor part provided toward the front end inserted into the female connector, the anchor part being secured to the bottom and the side surface of the female connector; and a press-fit part provided at a portion of lower insertion depth than that of the anchor part, the press-fit part being connected to a through hole of a lead pattern.
