Embodiment 1

[0065] First, prepare an insulating substrate whose main component is Al 2 o 3 On one surface of a thinned green body made of a material composed of a glass component, an Ag paste is printed by screen printing to a thickness of about 10 μm after firing to form a pair of band-shaped first opposite sides. The pattern of the electrode 12 and the second counter electrode 13. The length of the electrodes 12 and 13 after printing was 0.5 mm, the width was 0.4 mm, and the distance ΔG between the electrodes was 30 μm.

[0066] Next, acrylic resin was mixed with butyl carbitol to prepare a paste-like mixture for space formation with a solid content concentration for space 31 formation of 40% by mass.

[0067] The obtained paste-like mixture is formed on the above-mentioned first insulating substrate 19 and on the first opposing electrode 12 and the second opposing electrode 13 so as to cover the insulating surface of the first insulating substrate 19 and the opposing electrodes 12, 13....

Embodiment 2

[0072] Except that the insulating inorganic material forming the discharge triggering part 14 becomes 90 vol%, and the conductive inorganic material becomes 10 vol%, the mode is weighed, and others are all operated in the same manner as in Example 1, thereby obtaining the electrostatic discharge protection element of Example 2. .

Embodiment 3

[0074] Except that the insulating inorganic material forming the discharge trigger part 14 becomes 50 vol%, and the conductive inorganic material becomes 50 vol%, the mode is weighed, and others are all operated in the same manner as in Example 1, thereby obtaining the electrostatic discharge protection element of Example 3. .

Abstract

The present invention relates to an electrostatic discharge protection element the insulation resistance of which is not reduced in a short time when the element works at high temperature and is applied with a voltage. The electrostatic discharge protection device comprises an insulating laminate, a first opposing electrode, a second opposing electrode and a discharge inducing section, wherein the insulating laminate is provided with a first insulating substrate and a second insulating substrate; the first and second opposing electrodes are disposed between the first insulating substrate and the second insulating substrate in an opposite maner; and the discharge inducing section is disposed apart from the front end of the first opposing electrode and the front end of the second opposing electrode. The insulation resistance of the electrostatic discharge protection element is not reduced in a short time when the element works at high temperature and is applied with a voltage.

Description

technical field [0001] The present invention relates to an electrostatic discharge protection element, and particularly relates to an electrostatic discharge protection element useful for use in a high-speed transmission system or in combination with a common mode filter. Background technique [0002] In recent years, the miniaturization and performance enhancement of electronic devices are rapidly progressing. Furthermore, as represented by high-speed transmission systems such as antenna circuits such as mobile phones, RF components, USB2.0 and USB3.0, S-ATA2, HDMI (registered trademark), the increase in transmission speed and the characteristics of circuit components used Significant progress has been made in lowering the driving voltage. With the miniaturization of electronic equipment and lower driving voltage of circuit elements, the withstand voltage of electronic components used in electronic equipment has decreased. Therefore, it is an important technical issue to ...
