Abstract

PURPOSE:To provide a semiconductor device which is miniaturized in size by arranging a member of controlling the di/dt values on the periphery of a semiconductor element and yet inside a cooling wind tunnel so that both the control member and the semiconductor element are cooled at the same time within the common cooling device wind tunnel. CONSTITUTION:In power rectifiers, inverters, switches, breakers, and the like, a flat type semiconductor element 1 is additionally equipped, for example, with a cylindrically shaped core 2 made of iron to produce inductance so that the transient di/dt values of the semiconductor element 1 may be controlled. A cooling fin 4 is fitted to both electrodes of the element 1, with the iron core 2 provided between the periphery of the element 1 and the cooling fin 4. The thus formed composite is placed within a wind tunnel 9 to be cooled, using a cooling fan 6. The iron core tends to become exothermic by hysteresis loss, but since it is situated near to the element 1 within the wind tunnel 9, no extra cooling means to be used exclusively for cooling the iron core may be required any longer. This is why the semiconductor device can be made smaller sized.
