I have a few projects coming up; they all need to switch higher current (.5 to 6 amps) at about 12 volts.
I think I have picked out a MOSFET that can be driven by the arduino:
But i'd really like it if somebody could take a quick look at the specs to tell me if i am reading them correctly.
FET Feature Logic Level Gate This means that the gate is activated by lower voltages Rds On (Max) @ Id, Vgs 12.8 mOhm @ 30A, 10V This is the amount of internal resistance between the source and load Drain to Source Voltage (Vdss) 25V This is the maximum voltage that this MOSFET can switch Current - Continuous Drain (Id) @ 25° C 30A This is the maximum amount of current that can flow through MOSFET Vgs(th) (Max) @ Id 2V @ 20µA This is amount of voltage (and current) needed to switch on Gate Charge (Qg) @ Vgs 8.3nC @ 5V Amount of capacitance that this MOSFET will introduce into circuit Input Capacitance (Ciss) @ Vds 1043pF @ 15V I don't know what this means Power - Max 46W this is the maximum amount of current and voltage that can pass through the device
things in Yellow - are not clear to me things in Red - are things i do not understand. things in Blue - I think i understand, but would like your feedback
Thanks for your time (yes, i realise this is somewhat like a few posts that exist already, but those were not entirely clear or did not mention all of the measurements i have a question about.)
