Hello ! Myself Sanjay, I wanted to model the MOSFET switching losses, and true, there is a part in the library (MOSFET with limited di/dt) but if I’m not mistaken, the MOSFET turn off depends on the load current and isn… --- ## [Mosfet library plecs power losses](https://forum.plexim.com/t/mosfet-library-plecs-power-losses/599)
