<p>PURPOSE:To lower the series resistance of a diode without making operating efficiency lower than conventional devices by connecting a lead terminal and a chip electrode in parallel while the upper section of the chip electrode is used as a turning point. CONSTITUTION:A diode is composed of a diode chip 2 being fixed onto a substrate 1 and having a chip electrode 3, lead terminals 4 oppositely arranged to the substrate 1, and wires 6 connecting the lead terminals 4 and the chip electrode 3 in parallel while the upper section of the chip electrode 3 is employed as a turning point. The diode chip 2 is fastened to the substrate 1, the wire 6 is connected to the chip electrode 3 from the lead terminal 4, and the wire 6 is folded back and connected to the lead terminal 4 from the chip electrode 3 as the procedure of the assembly. Lastly, an outer circumference is covered under the state in which the substrate 1 and the nose sections of the lead terminals 4 are exposed, and the whole is sealed with a molding resin 7 as shown in a broken line. Accordingly, the series resistance of the diode can be made lower than one wire as seen in conventional devices.</p> |
