The IRF540N N-Channel MOSFET is a power MOSFET for high-efficiency switching applications. It offers much lower on-resistance than bipolar transistors, making it ideal for PWM motor control, power switching, and high-current load driving.
Key features
- N-Channel power MOSFET
- Low RDS(on) (~0.077Ω)
- 33A continuous drain current
- 100V drain-source voltage
- TO-220 package
- High efficiency switching
- Fast switching speed
Good to know
- Logic-level gate drive may need pull-down resistor
- Gate capacitance requires driver for high-frequency PWM
- Heatsink needed for high continuous current
- Add flyback diode for inductive loads
- Switch fully on or off – avoid linear region for efficiency
- Verify gate threshold voltage for your drive voltage
