Abstract :
Detailed measurements have been made of the base and collector-current characteristics of both n-p-n and p-n-p silicon transistors as a function of temperature. The collector current shows ideal behavior over the temperature range -60 to 150°C in that 
. On the other hand, the base current is nonideal: 
, where 
. The nonideality of IB is the main source of the temperature dependence of 
. There is no evidence for bandgap narrowing in the devices we have investigated. The temperature dependence of the collector current is given by

eV. This result is consistent with the findings of others. The base current is a complicated function of temperature due to the presence of nonideal components.
