THERMAL DATA
K Package:
Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).
Note B. The above numbers forθJC aremaximumsforthelimitingthermal
resistance of the package in a standard mounting 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.
