MOSFET model with parameters' dependency on temperature.

So I am looking for a Simscape Electrical block for a MOSFET allowing me to parameterize the following properties as look-up tables:

• transistor forward threshold voltage as a function of temperature
• transistor on-state resistance as a function of temperature
• transistor turn-on switching energy as a function of voltage, current, and temperature
• transistor turn-off switching energy as a function of voltage, current, and temperature

Furthermore, I am interested in having a thermal port available enabled for this block so I can study cooling options of this and other devices around it.

I have look everywhere and I haven't been able to find a block covering all my previous requirements, did I miss something here? is there any workaround?

thanks a lot!

Currently, Simscape Electrical does not provide a single MOSFET block that supports all the parameterization options you listed. While some blocks allow partial parameterization (check out MOSFET (Ideal, Switching) for example), comprehensive look-up table support for all those properties is not built-in. As a workaround, you can use the Simscape language to create a custom MOSFET block that incorporates these dependencies. This approach requires some modeling effort, but it allows you to achieve the level of detail and flexibility you need.
