For most applications P

P

and can be neglected. P
PORT
may become significant if the de-
vice is configured to drive Darlington bases or sink LED loads.
An approximate relationship between P
D
and T
J
(if P
PORT
is neglected) is:
2. P
D
= K
(T

Solving equations 1 and 2 for K gives:
3. K = P

Where K is a constant pertaining to the particular part. K can be determined from equation 3 by mea-
suring P
D
(at equilibrium) for a known T
A
. Using this value of K the values of P
D
and T
J
can be obtained
by solving equations 1 and 2 iteratively for any value of T
A
.
