Data Sheet - Absolute Maximum Ratings

5 Absolute Maximum Ratings

Stresses beyond those listed in may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated in Electrical Characteristics

on page 4 is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device

reliability.

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 (TA-MAX)

is dependent on the maximum operating

junction temperature (TJ-MAX-OP =

125ºC), the maximum power dissipation

of the device in the application (PD-MAX),

and the junction-to ambient thermal

resistance of the part/package in the

application (θJA), as given by the

following

equation: TA-MAX = TJ-MAX-OP – (θJA ×

PD-MAX).
