Found on Mouser two choices:

At 0,781 euros per piece IRFIZ24NPBF, a 55V/13A, 70mOhm, Vth at 1.8V https://gr.mouser.com/ProductDetail/...E5KLNbCg%3D%3D

At 2,23 euros per piece FDP070AN06A0, a 60V/15A, 7mOhm. Vth at 2V. https://gr.mouser.com/ProductDetail/...Y6Zv7sew%3D%3D

With the second the power dissipation at 2A will be 0,028 Watts !!!

With the first 280mW. Also pretty good I guess.

Note that the first is marked as LC (reaching end of life or something).
