我们给出一个关系式，它把发射极和集电极结电压V eb和V eb，集电极电流Ic，以及通过基极端子进入的载流子（pnp晶体管中的电子）的总电荷Q B联系起来：$I_{c} = const{e^（aV_{eb/kT}）- e^（aV_{eb / kT}）over Q_{B}}。$该关系式对于高喷射条件是有效的，仅受较小的限制。讨论了器件建模的意义。
We give a relation which links emitter and collector junction voltages, V eb and V eb , collector current I c , and the total charge Q b of carriers that enter through the base terminal (electrons in a pnp transistor): $I_{c} = const{e^(aV_{eb / kT}) - e^(aV_{eb / kT})over Q_{b}}.$ This relation is valid for high injection conditions, subject only to minor restrictions. The significance for device modeling is discussed.
