Effect of collector voltage and collector current on junction temperature

open access: yesElectronics Letters, 1965
Experiments have been carried out on the 2N929 transistor to investigate the effect of collector voltage and collector current on junction temperature. The results indicate that at constant power dissipation increasing the collector voltage will increase the junction temperature and give the apparent effect of a higher thermal resistance.
