PWM DC Motor Speed Control

The IRF520 PWM MOSFET Module can be used for speed control of compatible small DC motors by switching the motor supply using a PWM signal.

Changing the PWM duty cycle changes the average power delivered to the motor, allowing its speed to be adjusted within the limits of the motor and switching circuit.

The module provides single-direction low-side switching. It is not an H-bridge motor driver and cannot independently reverse motor direction.

LED Brightness Control

The IRF520 module can also be used for PWM dimming of compatible DC LED strips and lighting circuits.

A microcontroller-generated PWM signal controls the MOSFET switching operation to adjust the average power supplied to the LEDs.

For higher-current lighting systems, a logic-level MOSFET or properly driven power MOSFET is recommended to reduce heating and improve switching efficiency.

Typical Module Connections

• SIG: Digital or PWM control signal
• VCC: Control-side supply connection where fitted
• GND: Control circuit ground
• VIN / Load Supply: Positive DC load supply
• V+ / V-: Load output connections on common modules

Note: Connection names and PCB layouts vary by manufacturer. Always verify the actual board's printed labels and circuit connections before applying power.

IRF520 MOSFET Switching Technology

The IRF520 is an N-channel enhancement-mode power MOSFET designed for electronic switching applications.

It controls current flow through a load by applying an appropriate gate-to-source voltage. When properly driven, the MOSFET can switch DC loads electronically without mechanical relay contacts.

Unlike mechanical relays, MOSFETs can support rapid switching and PWM operation when the gate drive, operating frequency, and thermal conditions are suitable.

IRF520 Module vs Logic-Level MOSFET Module

The IRF520 is commonly used in educational MOSFET modules, but it is not optimized for direct high-current switching from low-voltage microcontroller GPIO pins.

• IRF520 Module: Suitable for learning PWM switching and modest DC loads with appropriate gate drive.
• Logic-Level MOSFET Module: Preferable for direct 3.3V or 5V switching when the MOSFET is specifically rated for those gate voltages.

For demanding DC motor, heater, or LED applications, select a MOSFET module with verified current ratings and adequate cooling.

Important Safety and Usage Notes

• Use DC loads only; do not connect directly to AC mains.
• The IRF520 is not a true logic-level MOSFET.
• Do not assume 3.3V or 5V control signals will fully turn on the MOSFET.
• The MOSFET's 9.2A transistor rating is not the continuous current rating of the assembled module.
• Check module temperature during operation.
• Provide adequate cooling for higher-current applications.
• Use a suitable flyback diode across inductive loads such as motors and solenoids.
• Observe correct polarity and wiring connections.
• Use a separate, appropriately rated supply for the connected load.
• Verify PCB, terminal, wire, and MOSFET ratings before use.
• Do not exceed the manufacturer's electrical and thermal limits.
