Precision Electrothermal MOSFET models

Validating circuit designs when using Power MOSFETs can be a challenging process. Accurate modelling of the dynamic characteristics of the device is key to EMI consideration. If the model is not realistic, EMC problems cannot be recognized thereby causing issues down the line, likely when the designer has already committed to layout.

With Nexperia's new electrothermal MOSFET model, the engineer is provided the capability to validate their circuit design during the preliminary stage of the project.

Below is a list of products that have the electro thermal models available, you can find the models in the support tab.
