IRF540 MOSFET N-Channel 33A 100V
The IRF540 N-Channel MOSFET is a high-performance power transistor in a robust TO-220AB package. It handles a continuous drain current of 33A, a drain-source voltage up to 100V, and dissipates up to 130W with a low on-resistance of 44 mΩ. Ideal for motor control, power supplies, inverters, high-current switching, and load driving from Arduino, Raspberry Pi, and other microcontrollers — with pulse current up to 110A for demanding applications.

The IRF540 is a widely used N-channel power MOSFET designed for high-current switching and amplification in industrial, automotive, and DIY electronics applications. Built into the rugged TO-220AB through-hole package, it provides excellent thermal performance and is easy to mount on standard heatsinks for sustained high-power operation.
With a maximum drain-source voltage of 100V, continuous drain current of 33A, and a pulsed current capability of up to 110A, the IRF540 is well suited for driving heavy loads such as DC motors, solenoids, high-power LEDs, lamps, heaters, and inverters. Its low on-resistance (RDS(on)) of just 44 mΩ keeps power losses minimal, allowing the transistor to switch high currents efficiently with reduced heat generation.
The IRF540 supports a wide operating junction temperature range from −55°C to +175°C, making it reliable in demanding environments. Its 130W power dissipation rating and low thermal resistance (junction-to-case) of 1.1°C/W allow it to handle continuous high-power switching when properly heatsinked.
Note on gate drive: The IRF540 is not a logic-level MOSFET — it typically requires a gate-source voltage of around 10V for full enhancement. To switch the IRF540 reliably from a 5V Arduino or 3.3V microcontroller, use a dedicated MOSFET gate driver IC or a small NPN/PNP driver stage. For direct logic-level driving, consider the IRF540N's logic-level cousins like the IRL540 or IRLZ44N.
