Caution:

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;

functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be

affected by exposure to absolute maximum rating conditions for extended periods of time.

Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling

and transporting these devices.

Notes:

4. UL Recognized Rating from -30°C to +70°C (Diodes Incorporated qualified TST from -65°C to +150°C).

5. External capacitors need to be connected to the output, EVM board was tested with capacitor 2.2

μF 50V 0805.

This level is a pass test only and not a limit.
