<P>PROBLEM TO BE SOLVED: To reduce stray capacitance of a power module output terminal part and to suppress charging/discharging current due to it. <P>SOLUTION: IGBT 3a and FWD 4a, and IGBT 3b and FWD 4b are connected to be antiparallel, and they are laminated and arranged so that they are connected in series. A circuit pattern 10a is a positive electrode on an upper arm-side, and a collector electrode of an IGBT chip 3a and a cathode electrode of FWD 4a are fixed to it. An electrode 2c becoming an output terminal is fixed or is press-fitted to an emitter electrode-side of IGBT 3a, and it is directly taken out from a module 2 as an external electrode. The terminal is directly wired with an external part without the aid of an insulating substrate 10. Thus, stray capacitance is reduced and charging/discharging current is suppressed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
