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

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply for the operating ambient temperature of T
A = 25°C.
Low duty cycle pulse testing tech-
niques are used which maintains junction and case temperatures equal to the ambient temperature.)
