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.

1 The information in this section is based on simulated thermal information.

2 These values apply to the package with no heat sink attached. The actual

thermal performance of the package depends on the attached heat sink and

environmental conditions.

3 Natural convection at 55°C ambient. Assumes perfect thermal contact

between the cooling plate and the exposed paddle.

3 N/A means not applicable.
