IRF540N MOSFET 100V 33A N-Channel Power Transistor | Compoden
IRF540N MOSFET – 100V, 33A N-Channel Power Transistor
The IRF540N is an N-channel power MOSFET designed for high-speed switching applications. With a drain-source voltage rating of 100V and a continuous drain current of 33A, it is suitable for driving motors, solenoids, and LEDs. Its low on-resistance of 44mΩ ensures minimal power loss and heat generation.

- High-power LED dimmer or strobe driver
- Solenoid or relay driver for automation
- DC-DC converter or power supply switch
Compatibility
The IRF540N works with 3.3V and 5V logic microcontrollers like Arduino, ESP32, and Raspberry Pi, but for full enhancement, a gate drive voltage of 10V is recommended. Use a logic-level MOSFET driver or a transistor-based level shifter if driving directly from 3.3V logic. It pairs well with popular motor driver ICs and H-bridge configurations.
Wiring Notes
Connect gate to your control signal through a 100Ω resistor to limit inrush current. Add a 10kΩ pull-down resistor from gate to source to prevent floating state. Ensure the source pin is connected to ground for N-channel switching.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the IRF540N can be directly driven by an Arduino pin when using a 5V output, but for 3.3V boards, a logic-level converter or driver is recommended to achieve full switching capability.
What gate voltage is needed to fully turn on?
A gate-source voltage of 10V ensures the MOSFET is fully enhanced with minimal resistance. At 5V, it may still conduct but with higher Rds(on).
Can I use this for high-frequency PWM?
Yes, the IRF540N handles switching frequencies up to several hundred kHz, but gate charge and drive requirements should be considered to minimize switching losses.
