Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

ENVIRONMENTAL CONDITIONS

Ambient Temperature Rating

TAMB = TCASE − (PD × θCA)

where:

TCASE is the case temperature in °C,

PD is the power dissipation in W,

θCA is the thermal resistance (case-to-ambient),

θJA is the thermal resistance (junction-to-ambient),

θJC is the thermal resistance (junction-to-case).
