Description:
The 2N7000 is a widely available and popular part, often recommended as useful and common components to have around for hobbyist use. The 2N7000 has been referred to as a "FETlington" and as an "absolutely ideal hacker part. The word "FETlington" is a reference to the Darlington-transistor-like saturation characteristic.
Product highlights:

MOSFET Transistor |
| Working principle |
N-channel |
| Pin configuration |
G = Gate, D = Drain, S = Source. The symbol doesn't always show the internal diode formed between the substrate and the source/drain/channel. |

Advantages:
- the high input impedance of the insulated gate means almost no gate current is required
- consequently, no current-limiting resistor is required in the gate input
- MOSFETs, unlike PN junction devices (such as LEDs), can be paralleled because resistance increases with temperature, although the quality of this load balance is largely dependent on the internal chemistry of each individual MOSFET in the circuit
