If you've ever wondered how to control the headlight of a car from a microcontroller, a MOSFET is what you need. The RFP30N06LE is a very common MOSFET with very low on-resistance and a control voltage (aka gate voltage) that is ideal for using with any 3-5V microcontroller or mechanical switch. This allows you to control high-power devices with very low-power control mechanisms.

Great product I currently use a 3.3v pro mini to switch a larger current system. This is with the inbuilt pull up resistor. Hours of tests and no problems so far.

Have you tried using a higher value pull down resistor say 100k?

I'm using this MOSFET with a raspberry pi GPIO pins just to switch on an LED. 3.3v from the GPIO (or the 3.3v header pin) doesn't seem to be enough to switch it. 5v from the supply does work.
Currently using another one of these as a level converter; ( http://elinux.org/RPi_GPIO_Interface_Circuits ) until I find a better solution

a common part but you want well made when using it to connect a arduino pwm output to some 15-30w LED's
