Problems solved by technology

However, chip-type components that form a relatively small package shape do not have a heat dissipation mechanism, and resin is used on the outside, so it is difficult to effectively dissipate the heat emitted by the light-emitting diodes.

Abstract

An electrostatic discharge protection component comprises a ceramic sintered body having ceramic substrate 12, varistor portion 10 formed thereon, and glass ceramic layer 14 formed further thereon, a pair of terminal electrodes 13a, 13b provided on the surface of this ceramic sintered body, a pair of external electrodes 16a, 16b, and heat conducting portion 15 penetrating through the ceramic sintered body vertically, and therefore by mounting the light-emitting diode on heat conducting portion 15 of this electrostatic discharge protection component, the size is reduced, and the heat generated from the component may be released efficiently.

Description

technical field [0001] The present invention relates to a static electricity countermeasure component used in various electronic equipment as an electronic component protecting the electronic equipment from static electricity, and an electronic component module such as a light emitting diode 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 the circuits of the electronic devices has gradually decreased. [0003] Therefore, failure disturbances of electronic equipment caused by damage to various electronic equipment, especially semiconductor devices, caused by electrostatic pulses generated when the human body comes into contact with the conductive portion of the electronic equipment are increasing. [0004] In addition, li...
