<P>PROBLEM TO BE SOLVED: To provide a semiconductor device which can reduce a convergence time of a vibration phenomenon occurring during reverse recovery operation of a reflux diode. <P>SOLUTION: The semiconductor device includes the reflux diode 100 which performs unipolar action, and a semiconductor snubber 200 which is connected to the reflux diode 100 in parallel, and includes a semiconductor substrate region. The semiconductor snubber 200 includes a capacitor 210 formed at least on one end side of the substrate region during reverse bias of the reflux diode 100, a resistance 220 including a part of the substrate region, and a reverse blocking diode 222 formed on at least a part of the substrate region so as to be in a reverse blocking state with respect to forward bias of the reflux diode 100. <P>COPYRIGHT: (C)2010,JPO&INPIT |
