The 2N7000 is a handy N-channel MOSFET capable of continuously driving up to 200mA.
This type of MOSFET is often referred to as a logicl level FET since it has a very low gate threshold voltage of around 2.1V. This makes it great for use with digital circuits and signals from devices such as Arduino and even Raspberry Pi.
The 2N7000 works well as a gate driver for larger MOSFETs that require a higher gate threshold voltage but that you want to control with a smaller voltage such as 5V or 3.3V.
