Teaching how to fish.................
Go to any parts vendor. digikey.com for example.
In the search window type MOSFET.
Because FETs are everywhere you might have to choose a small group like "discreet parts", then single/dual/modules (pick single).
Digikey has only 32,000 typed of MOSFETs in single packages. Now pick a voltage range and (either a current or on resistance) range.
You can pick what package type etc.
There is likely a check box or button to 'show me only parts in stock'.
good luck
