Longevity
The Nexperia Longevity Program is aimed to provide our customers information from time to time about the expected time that our products can be ordered. The NLP is reviewed and updated regularly by our Executive Management Team. View our longevity program here.
How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
