A high-side P-channel FET with an extremely low gate voltage which can be controlled by most 3.3V and 5V microcontrollers.
The NDP6020P is a useful P-Channel FET that is compatible with most 3.3V and 5V microcontrollers. it has a very low gate threshold voltage (VGSth) of 2V to provide s nice 8 Amps. As you increase the gate voltage to 3.3V or higher the full current capability is available.
"High-side" means you are placing this FET above the load, so it's between the power supply (+) and the device (which in turn is connected to ground).
Mike Tranchemontagne produced a nice Youtube video showing the ins-and-outs of using this particular device. Thanks, Mike!
