ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000

Notes

a. Device mounted with all bumps soldered to PC board

b. Derate 9.1 mW/°C above TA = 70 °C



Stresses beyond those listed under "Absolute Maximum Ratings" 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 the operational sections of the specifications is not implied. Exposure to absolute maximum

rating/conditions for extended periods may affect device reliability.

Notes

a. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum

b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing

c. For VIN outside this range consult typical EN threshold curve
