DWP PACKAGE:
THERMAL RESISTANCE-JUNCTION TO LEADS, θJL
18°C/W
THERMAL RESISTANCE-JUNCTION TO AMBIENT, θJA
40°C/W
Junction Temperature Calculation: TJ = TA + (PD x θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board
system. All of the above assume no ambient airflow.

ELECTRICAL CHARACTERISTICS
Term Power = 4.75V unless otherwise specified. Unless otherwise specified, these specifications apply at the recommended operating ambient tempera-
ture of T = 25°C. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.
