About this product
The IRF540 is an N-channel power MOSFET in a TO-220 package, rated for 100V drain-source voltage and 33A continuous drain current, with 0.044Ω on-resistance as listed. It is suited to switching high-current loads such as DC motors, lamps and solenoids, and to power switching in driver and converter circuits. Its gate needs roughly 10V for full enhancement.

Frequently asked questions
What is the price of IRF540 N-Channel Power MOSFET 100V 33A 0.044Ω TO-220 in Egypt?
IRF540 N-Channel Power MOSFET 100V 33A 0.044Ω TO-220 currently costs between 15 and 25 EGP across 2 offers in Egypt.
Where can I buy IRF540 N-Channel Power MOSFET 100V 33A 0.044Ω TO-220 in Egypt?
IRF540 N-Channel Power MOSFET 100V 33A 0.044Ω TO-220 is available from Makers Electronics and Circuits Electronics. Compare the offers above to find the best price.
Can I drive the IRF540 from a 5V Arduino pin?
Not reliably. The IRF540 is a standard-level MOSFET and needs about 10V on its gate for full switching, so a 5V pin leaves its on-resistance much higher and the device hot. For direct 5V drive, use a logic-level MOSFET such as the IRL540, or add a gate driver.
Do I need a protection diode when switching motors or solenoids with the IRF540?
Yes, for inductive loads. Place a flyback diode across the motor or solenoid, with its cathode to the positive supply, to absorb the voltage spike when the MOSFET turns off and protect the device.
