One considerable disadvantage of the IRF740 Mosfet is its high on-resistance (RDS) value which is about 0.55 ohms. If you prefer a mosfet with low gate voltage then try IRF540N or 2N7002 etc. Since the mosfet is for switching high current high voltage loads it has a relatively high gate voltage, hence cannot be used directly with a I/O pin of a CPU. The Mosfet could switch loads that consume upto 10A, it can turned on by provide a gate threshold voltage of 10V across the Gate and Source pin. The IRF740 is an N-Channel Power MOSFET which can switch loads upto 400V.
