Thermal Resistance Calculation For Bare Die
In order to relate the junction temperature to the temperature of the back side of the bare die, the following
thermal characteristics of the package are provided
Table 5: Thermal Resistance Calculation for Bare Die.

θJB = Thermal Resistance from Junction to back = 8°C/W
Example:
For VSC7711 at nominal supply current of 25mA and VDD = 5V
Temperature rise from junction to back = 0.025A x 5V x 8°C/W = 1°C
