THERMAL DATA
R Package:
Thermal Resistance-Junction to Case, θJC .................. 4.0°C/W
Thermal Resistance-Junction to Ambient, θJA .............. 40°C/W
Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).
Note B. The above numbers for θJC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing 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.

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