If you've ever wondered how to control the headlight of a car from a microcontroller, a MOSFET is what you need. This is a very common MOSFET with very low on-resistance and a control voltage (aka gate voltage) that is compatible with any 3-5V microcontroller or mechanical switch. This allows you to control high-power devices with very low-power control mechanisms.
**Note: **We stock two different models of this component, the two are nearly identical and can be used interchangeably. We've provided links to both datasheets below. We are currently shipping the FQP30N06L.
