(1) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (T
A(max)
) is dependent on the maximum operating junction temperature (T
J(max)
), the
maximum power dissipation of the device in the application (P
D(max)
), and the junction-to-ambient thermal resistance of the part/package
in the application ( θ
JA
), as given by the following equation: T
A(max)
= T
J(max)
– ( θ
JA
X P
D(max)
).
