Problems solved by technology

However, chip-type devices with a relatively small package shape do not have a heat dissipation mechanism and use resin for the exterior, so it is difficult to efficiently dissipate the heat emitted by the light-emitting diodes.

Abstract

The invention provides an electrostatic discharge protection component, and electronic component module using the same. An electrostatic discharge protection component comprises a ceramic sintered body having ceramic substrate 12, varistor portion 10 formed thereon by avoiding a part of non-forming area 18, and glass ceramic layer 14 formed thereon, a par of terminal electrodes 13 a, 13 b provided on the surface of glass ceramic layer 14 of the ceramic sintered body, a pair of external electrodes 16 a, 16 b, and heat conducting portion 15 penetrating through ceramic substrate 12 vertically, and therefore by installing and mounting a light-emitting diode on heat conducting portion 15 in non-forming area 18 of the electrostatic discharge protection component, the size can be reduced, and the heat generated by the mounted component may be released efficiently.

Description

technical field [0001] The present invention relates to a static electricity countermeasure component that is an electronic component used in various electronic equipment to protect the electronic equipment from static electricity, and an electronic component module using the static electricity countermeasure component. Background technique [0002] In recent years, the miniaturization and low power consumption of electronic devices such as mobile phones have rapidly progressed, and with this, the withstand voltage of various electronic components constituting circuits of the electronic devices has decreased. [0003] Therefore, failures of electronic equipment due to destruction of various electronic components, particularly semiconductor devices, due to electrostatic pulses generated when the human body comes into contact with the conductive portion of the electronic equipment increase. [0004] In addition, light-emitting diodes, which are one type of semiconductor device...
