So if you were to suggest a Mosfet that I could use on a logic level what would be your suggestion? I need one that will operate at a minimum of 20 amps but other than that, voltage wise Is pretty flexible probably 12 volts minimum.
There are many 1000’s if not 10,000’s of MOSFETs available - the first thing to do is find
a good electronics supplier, rather than be limited to the few lines that crop up on eBay or
sparkfun etc. A good supplier will have a website search tool to search for devices according
to its specifications.
Key specs are voltage, on-resistance, gate drive voltage (ie <= 5V for logic-level, 10V for non logic level),
package type, total gate charge, n-channel or p-channel…
