(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
MAX
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.)

THERMAL DATA
Note A. Junction Temperature Calculation: T

= T
A
+ (P
D
x θ
JA
).
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.
