摘要
在半导体放电管的版面设计上提出了多元胞结构版图 .对多元胞结构“短路模型”进行了理论分析和实验验证 ,结果表明合理设计多元胞版图尺寸和 P基区薄层电阻可以改善器件的转折导通特性和提高器件的抗雷电浪涌能力 。
Semiconductor arrestor is a new type of transient voltage suppressor, whose novel multi\|cell structure is proposed. The model of “short” circuit for multi\|cell semiconductor arrestor has been studied by means of both theoretical analysis and experimental research. It is concluded that the breakover characteristics and the surge handling capability can be improved by selecting the proper size of cells and sheet resistance of p\|base, as provides a safe ground to simplify the production process.
