Hi all,
I'm new to this forum, and i really need an help:
I have to calculate Eon and Eoff of this mosfet (IPB50R140CP) but in the datasheet there is no plot about energy.
Someone got some advise to calculate these with for different Vds, Id, Vgs?
Also for the diode's recovery there is no plots, how can i calculate them with precision?
Thanks and sorry for my bad english

There are application notes regarding the calculation of power losses available like

Thanks a lot Schulz!
But for the recovery? Cause in IPB50R140CP 's datasheet there is really poor data about recovery (and also about Switch losses: NO plot about Eon Eoff).

On documents section i found a pdf where in the appendix there are curves of Eon and Eoff of some devices but no IPB50R140CP. Someone can tell me if i can use this with some adjustments
and if in the Eon curves there is also the the recovery loss?
and if in the Eon curves there is also the the recovery loss?
