Thermal Characterization Parameter, Psi-JT (
Ψ
JT
), is the “resistance” from junction to reference point
thermocouple on top center of case as defined in JESD51-2.
Ψ
JT
is a useful value to use to estimate junction
temperature in steady-state customer environments.
Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and
board thermal resistance.
See Section 5.1 from more details on thermal design considerations.
TJ = Junction Temperature
TA = Ambient Temperature
