Diode

Abstract

Abstract PURPOSE:To omit a resistance element heretofore externally attached and to reduce a circuit configuration by forming a resistance element in series with a diode element on the same chip. CONSTITUTION:A structure in which a resistance element 3 is internally connected to the anode terminal A of the diode element 2 of a diode 1 containing a resistor therein on the same chip is formed. For example, in case of a filter circuit 11, it has a property that, when a forward current flows, the resistive component of the element drops. When the diode 2 is turned ON (biased positively to +B) by utilizing this property, an inductance L2 is short-circuited, the inductance of the circuit 11 becomes only an inductance L1. When the diode 2 is turned OFF (not biased to +B), the inductance component of the circuit 11 becomes the sum of the inductances L2 and L1.
