New description: [New technical field] This is a kind of wafer type electrostatic protection component with overvoltage protection function. In particular, it refers to the introduction of ESD electrostatic discharge protection component into 〇VP overvoltage protection component. The advantages of the combination, so that the electronic products toward the light, thin, point, small concept development, so that the product is more miniaturized. [Prior Art] A laminated varistor (MLV), as shown in Figs. 1 and 2, includes a body portion 10 extending from both side ends of the body portion to the inside of the body portion, respectively. Electrodes 101, 102, 103, 104.... terminal electrodes 20 disposed at both ends of the body portion, and a coating layer 30 disposed on the top surface of the body portion, wherein the body portion is more than 9 inches The percentage (mole%) of the oxidized word (Zn〇) is the main component, and other metals such as cobalt (Co), manganese (Mn), and (b) are mixed under a mole percent (m〇le%). ), chromium (Cr), nickel (Ni), titanium (Ti), tin (Sn), lanthanum (La), yttrium (Nd), yttrium (pr), barium (Ba), magnesium (Mg), cerium (Ce ), an oxide such as boron (Bi) as an additive, and a sintering aid (flux) such as nitric acid [αι2 ( Ν〇3) χ), glass (Glass), and cerium oxide (Sil2). a metal such as gold (Au), silver (Ag), palladium (Pd), turn (Pt), rhenium (Rh), or a combination thereof, to the internal electrode 101, 1 2 1〇3,... • · · 〇101, 102, i In the laminated varistor, the overlapping areas A, B, and c between the internal electrodes 5 M333000 103, 104, that is, the 'active area~ the active area has 彡, 纟A has a 琶 resistance, and has both capacitive characteristics. . The structure of the region is as shown in Fig. 2, and the Zn 〇 grains are closely arranged between the regions where the two internal electrodes 101 and 102; 102 and 103; 103 and 104 overlap. The above-mentioned laminated varistor generally controls the component's breakdown voltage (Vb), anti-surge capability and element capacitance by changing the material ratio, thickness and number of layers of the active region. Value (Capacitance). However, the above method of using the material formula of the changing action area to improve the electrostatic protection ability is not appropriate, and the material formula of the dragon domain is affected by the overvoltage protection capability and the electrical performance. [New content] In view of the shortcomings of the aforementioned prior art, the creator is based on the manufacturing experience and technology accumulation of the overcurrent protection component, and carefully studies various solutions to the above-mentioned deficiencies. After continuous research and improvement, the design is finally developed. Out of the 劓 劓 from u Λ % and instinct of this creation, the period can be produced by the lack of. Therefore, the work & gram is designed to provide a smash-type electrostatic protection element with over-voltage protection function. In the production process, the inner layer electrode 2 is turned on, then the laser cutting, cutting machine, etc. are used. Cutting side = the inner electrode that is turned on at both ends is cut and separated'. It is formed into an air chamber after cutting, and has the function of ESD electrostatic discharge protection. Become the middle 6 M333000 [Simple description of the diagram] The first picture is a partial cross-sectional view of the see-through laminated varistor (MLV).
