THERMAL DATA
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.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply for the operating ambient temperature of T
=
25°C. V
= 14V, I
= 500mA for V
and 10mA for V
and are for DC characteristics only. Low duty cycle pulse testing techniques are used which
maintains junction and case temperatures equal to the ambient temperature.)
