Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

THERMAL RESISTANCE

Thermal performance is directly linked to printed circuit board

(PCB) design and operating environment. Careful attention to

PCB thermal design is required.

Typical θJA and θJC are specified vs. the number of PCB layers.

The use of appropriate thermal management techniques is

recommended to ensure the maximum junction temperature

does not exceed the limits shown in Table 8.

The maximum junction temperature of 125°C cannot be exceeded.

Per JEDEC JESD51-12.

For nonstandardized testing where the paddle of the device is directly

connected to a cold plate. This approach can be useful to estimate junction

temperature when the exact paddle temperature is known in the application.
