Sample
As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.
Sample orders normally take 2-4 days for delivery.
If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.
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.
