I recall some EPC suit saying that they would never sell a packaged
part.
At least, that\'s not much of a package.
I once used one of their smaller parts 0.9 mm * 0.9 mm
in a chopper amplifier to take advantage of the small
charge injection. It turned out to be easily soldered.
They call that thingie a power transistor.
I used the Altium part decals that EPC proposed. They have the
solder mask on part of the pads. JLCPCB asked back if I really
wanted it that way. I said yes and it worked nicely.

I like the tiny 4-ball parts, like EPC2038. Their drain-gate
capacitance is about zero so you can do stuff that wouldn\'t work with
mosfets.
They recommend solder-mask-defined pads but that\'s not really
necessary; the worst aligned thing on a PCB is usually the mask.
