It is commonly specified at 10 V gate drive for low RDS(on). For direct 3.3 V or 5 V control, verify the circuit or choose a logic-level MOSFET.\u003c\/p\u003e\n\u003ch4\u003eCan I use IRF540N with Arduino?\u003c\/h4\u003e\n\u003cp\u003eIt can be used in some Arduino circuits, but a 5 V gate signal may not fully turn it on for high-current loads.
