本文通过低频小信号合金型错晶体三极管的设计计算,介绍中、低频小功率合金型晶体三极管的设计方法,决定材料参数和结构参数应考虑的问题.晶体管的设计是根据电路对晶体管电学参数的要求来设计的.为了使晶体管具有一定的热稳定性,除了进行电学设计外,还要进行热学设计.而对于小功率管,只需采用金属外壳和基极接外壳的结构,就可达到散热的要求,不必另外采取其他热学措施.本文以电学设计为主.
In this paper, the design of low-frequency small-signal alloy transistor is introduced, and the design method of low-power and low-power alloy transistor is introduced to determine the material parameters and structural parameters that should be considered.The design of the transistor is based on the circuit’s electrical parameters In order to make the transistor has a certain thermal stability, in addition to the electrical design, but also for thermal design.While for low-power tube, only the use of metal shell and base shell connected to the structure, you can reach the heat The other thermal measure need not be taken separately.This paper mainly focuses on electrical design.
