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.

(T and L packages). Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the T and L
packages, and 20W for the K, R, and IG packages. I

is 1.5A for the K, R, and IG packages and 500mA for the T and L packages. Low duty cycle
pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
