<P>PROBLEM TO BE SOLVED: To solve the problem in which even the use of a parallel connection of a Schottky barrier diode DSB# (#=p,n) and a PiN diode DPN# as a freewheeling diode cannot necessarily reduce a surge voltage. <P>SOLUTION: A semiconductor chip TDp constituting a PiN diode DPNp is connected to an output side wire Lo via a bonding wire WD1, an inductance element 20 and a bonding wire WD2. A semiconductor chip TSp constituting a Schottky barrier diode DSBp is, on the other hand, connected to the output side wire Lo via a bonding wire WS. The inductance element 20 thus provided sets a higher inductance on the path for the PiN diode DPNp. <P>COPYRIGHT: (C)2013,JPO&INPIT |
