Hi,
I’ll use the irfz44n as an example to explain what i would like to know.
On the datasheet it sais max current is 49a, max voltage is 55v, resistance is 17.5mOhms and max power dissipation is 94w. When you calculate heat being produced, you get about 42w. I’m pretty sure that’s more than enough to make that transistor release its magic smoke so i’m wondering what the power dissipation means (it’s obviously not the amount of heat the thing can dissipate because that seems way too much) and how i can calculate max power.
