Description: 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.

I first came across this little thing via the MOSFET power controller listed here: https://www.sparkfun.com/products/10256
and found loads of fun and practical uses for the device.
taking the basic practical application of the device I resurrected a vintage traffic signal light by first gutting it,and then modifying a traditional 555 based LED traffic light simulator, replacing the LEDs with these MOSFET’s and using them to drive a bank of 12v DC lamps to make the old traffic light work through its functions as an accent lamp. the chip are a great value at the price point, and I highly recommend them
