Patent number: 9001485Abstract: An overvoltage protector includes a first discharging electrode, a second discharging electrode, and an overvoltage protection part provided between the first and second discharging electrodes. The overvoltage protecting part has an insulating property under a normal operation condition, and has a conductive property if an overvoltage is applied between the first and second discharging electrodes. The overvoltage protecting part is made of a mixture of resin having an insulation property, an inorganic compound having an insulating property, and metallic boride compound powder. The metallic boride compound powder has a high melting point therefore it is hardly melted. Under high temperatures causing the powder to melt, the powder is oxidized and loses conductivity, thus providing a high reliability.Type: GrantFiled: August 25, 2011Date of Patent: April 7, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kenji Nozoe, Hideaki Tokunaga, Takeshi Iseki, Takashi Morino, Kouichi Yoshioka

Publication number: 20100134235Abstract: A pair of thick first electrodes (2) are formed on an upper surface of alumina substrate (1) are formed with material having a low specific resistance. Thin second electrodes (3) that are positioned between first electrodes (2) and made of material having a high melting point are formed in a thin state. A gap (4) is formed between the second electrodes (3). First electrodes (2) forming connection electrodes are prevented from producing heat and protected from damage. The width of the gap between second electrodes (3) is narrow and accurate. This provides an electrostatic discharge (ESD) protector that is resistant to repetitive application of static electricity, reduces a peak voltage, and has a stable characteristic suppressing electrostatic discharge.Type: ApplicationFiled: June 19, 2008Publication date: June 3, 2010Applicant: Panasonic CorporationInventors: Kouichi Yoshioka, Masakatsu Nawate, Takashi Morino, Kenji Nozoe, Takeshi Iseki
