Freescale Semiconductor

Thermal Characterization Parameter, Psi-JT (

JT ), is the “resistance” from junction to reference point

thermocouple on top center of case as defined in JESD51-2.

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
