- 260 °C ESD Tolerance, HBM
(6)
- 1000 V Notes: (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specification are not implied. Exposure to absolute maximum rating conditions for extended periods may extremely reduce device reliability. (2) All voltages are with respect to GND plane. (3) Do NOT exceed more than 0.3V from Vin voltage. (4) The Trim pin is designed to be connected to GND via a resistor. (5) Recommended Reflow profile is written in “Soldering Guidelines”. (6) Human body model, per the JEDEC standard JS-001-2012.

-40 105 °C Junction Temperature -40 120 °C Load Current 0 4 A Notes: (1) This module should be operated inside the recommended operating conditions. This module has been designed and tested on the assumption that it will be used under the recommended operating conditions. Operating in not recommended condition may reduce reliability of the module. (2) See the temperature derating curves in the thermal deratings. However, do not condensate.

See “Fig.34” below for more information on our measurement conditions. (2) Junction thermal resistance is a function not only of the internal parts, but it is also extremely sensitive to the environment which includes, but is not limited to, board thickness, number of layers, copper weight / routes, and air flow. Attention to the board layout is necessary to realize expected thermal performance.
