Thermal Resistance Model for ACPL-K49U
The diagram of ACPL-K49U for measurement is shown in
Figure 13. Here, one die is heated  rst and the tempera-
tures of all the dice are recorded after thermal equilib-
rium is reached. Then, the 2
nd
die is heated and all the
dice temperatures are recorded. With the known ambient
temperature, the die junction temperature and power
dissipation, the thermal resistance can be calculated. The
thermal resistance calculation can be cast in matrix form.
This yields a 2 by 2 matrix for our case of two heat sources.
