In the case where the board temperature is known, use the

thermal characterization parameter, ΨJB, to estimate the

junction temperature rise (see Figure 49 and Figure 50).

Maximum junction temperature (TJ) is calculated from the

board temperature (TB) and power dissipation (PD) using the

following formula:

TJ = TB + (PD × ΨJB)

(5)

The typical value of ΨJB is 58°C/W for the 4-ball WLCSP package

and 43°C/W for the 5-lead TSOT package.
