Thermal Resistance Equations:
θJC = (TJ - TC)/P
θJA = (TJ - TA)/P
PMAX = (TJMAX - TAMAX)/ θJA
4/ (FOLSVH3OXV 'DWD 6KHHW 5HY $
Parameter Description:
θJC: Junction-to-case thermal resistance
θJA: Junction-to-ambient thermal resistance
TJ: Junction temperature
TA: Ambient temperature
P: Power dissipated by the device while operating
PMAX: The maximum power dissipation for the device
TJMAX: Maximum junction temperature
TAMAX: Maximum ambient temperature
NOTE: Maximum junction temperature (TJMAX) is 150º C. To calculate the maximum power
dissipation for a device package look up θJA from 7DEOH , pick an appropriate TAMAX and
use:
PMAX = (150º C - TAMAX)/ θJA
