I wan to dimmer an halogen lamp 12V DC 20W with PWM from Arduino Nano (3.3V). I was using an IRF520 Mosfet then a guy advice me to use an IRLZ44N, but didn't explain me why. I've tried to read the datasheet but my poor electronic knowledge didn't help me a lot.
What is the difference between the two components? Why I should use one instead the other?
