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 comprising a ceramic sintered body having ceramic substrate 12 , varistor portion 10 formed thereon excluding some non-formed portion 18 , and glass ceramic layer 14 further formed thereon, a pair of terminal electrodes 13 a, 13 b disposed by exposing a part thereof at non-formed portion 18 on ceramic substrate 12 of the ceramic sintered body, a pair of external electrodes 16 a, 16 b, and heat conducting portion 15 vertically penetrating ceramic substrate 12 , a light-emitting diode or the like mounted on heat conducting portion 15 at non-formed portion 18 , it is possible to reduce the size and to efficiently dissipate the heat generated by the component mounted.

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, malfunctions of electronic equipment due to damage to various electronic components, especially semiconductor devices, caused by electrostatic pulses or the like generated when the human body comes into contact with the conducting portion of the electronic equipment increase. [0004] Furthermore, light-...
