Abstract
An ESD protection component includes opposite electrodes and a ground electrode. The opposite electrodes and the ground electrode each have an extraction portion and an opposite portion. The respective opposite portions of the opposite electrodes and the ground electrode are placed on the same layer. At least one of the opposite electrodes and the ground electrode, the extraction portion and the opposite portion are placed on respective different layers and, also, are electrically connected to each other via a through hole conductor.
Claims4
An ESD protection component comprising:
- a element body including a plurality of insulator layers are stacked;
- a ground electrode placed inside the element body;
- a first opposite electrode which is placed to be spaced apart from the ground electrode and forms a discharging portion in cooperation with the ground electrode;
- a second opposite electrode which is placed to be spaced apart from the ground electrode and forms a discharging portion in cooperation with the ground electrode;
- and
- a plurality of external electrodes each being provided correspondingly to a respective one of the ground electrode, the first opposite electrode and the second opposite electrode;
- wherein
- the ground electrode, the first opposite electrode and the second opposite electrode are each adapted to have an extraction portion connected to the corresponding external electrode out of the plurality of the external electrodes, and an opposite portion which is electrically connected to the extraction portion and forms the discharging portion,
- the opposite portion of the ground electrode, the opposite portion of the first opposite electrode, and the opposite portion of the second opposite electrode are placed on the same layer, and
- in at least one of the ground electrode, the first opposite electrode and the second opposite electrode, the extraction portion and the opposite portion are placed on respective different layers and also are electrically connected to each other via a through hole conductor.
