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