DW Package:
Thermal Resistance-Junction to Case, θJC .................. 40°C/W
Thermal Resistance-Junction to Ambient, θJA ............. 95°C/W
L Package:
Thermal Resistance-Junction to Case, θJC .................. 35°C/W

Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).
Note B. The above numbers for θJC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The θJA numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.
