| 摘要 |
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 13 a, 13 b provided on the surface of this ceramic sintered body, a pair of external electrodes 16 a, 16 b, 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.
