In cases where the board temperature is known, the thermal
characterization parameter, Ψ JB , can be used to estimate the
junction temperature rise. Maximum junction temperature (T J )
is calculated from the board temperature (T B ) and power
dissipation (P D ) using the following formula:
Rev. F | Page 16 of 20
T J = T B + ( P D × Ψ JB )
