Take note, idiot, that the plastic cased part derates for every degree

That relects the Tj max of 150C.

So, IF you sink it well enough, it will do 626mW, HOWEVER, since it is
NOT at 25C from the onset of dissipation effects, that value is bogus for
free air operation. I don't expect you to understand, however.


That's complete nonsense. As to be expected from you.


Notice that at 600mA (*absolute* max per data sheet), the maximum Vce
is rather close to 1V as well as close to "saturation"?
Hey, if i am going to use a transistor as a switch, i will have to a
lot better than that!

There's no shortage of better devices to use as switches than a 2N2222.
