Abstract
A transient voltage absorbing element is provided that connected in shunt between a signal line on which inductors are connected in series and a reference potential. A first path connected in shunt between the signal line and the reference potential includes a diode including a first stray capacitance, a first parasitic inductor, and a first parasitic resistance that are connected in series. A second path connected in shunt between the signal line and the reference potential includes a second stray capacitance, a second parasitic inductor, and a second parasitic resistance that are connected in series. A capacitive property of a path formed between the signal line and the reference potential has frequency dependence. This capacitive property of the path is smaller in a frequency band of a signal that propagates through the signal line than in a frequency band other than the frequency band of the signal.
