This paper points out an error in the principle figure and the waveform figure of the thermal resistance standard IEC747 7, which describes the relation between the I V curves and the temperature. It theoretically proves that the I V T curve of the standard contradicts the physical law. This contradiction is also revealed by experimental results. Finally, the correct I V T characteristic curve and the waveform figure at two different temperatures for the same transistor is given, which serves as the reference to correct the standard.
