专利汇可以提供Transistor with improved breakdown mode专利检索,专利查询,专利分析的服务。并且There is disclosed a transistor with improved protection against excessive reverse biasing voltages. The improved protection is the result of providing a punch-through breakdown mode which is operative to the exclusion of an avalanche breakdown mode. In the improved transistor, the punch-through breakdown current is dissipated over a wide area such that little if any structural damage occurs. The provision of a punch-through breakdown to the exclusion of avalanche breakdown is accomplished by reducing the doping concentration in the base of the transistor under the emitter or by decreasing the distance between the collector-base junction and the emitter-base junction. There is further provided means for controlling the beta of the transistor as the distance between the above two junctions and the base doping concentration are reduced to provide for punch-through breakdown. Means are further provided for causing the punch-through breakdown to occur in a region either removed from the active area of the transistor or confined to a small portion of the active area of the transistor so that the punch-through mechanism does not interfere with the normal operation of the transistor. There is therefore separate control over the gain and the breakdown characteristics of the transistor. The punch-through current is made to flow to the emitter of the transistor whereby the punch-through breakdown current is dissipated over the entire emitter.,下面是Transistor with improved breakdown mode专利的具体信息内容。
