The 2N6800 is a dual-gate MOSFET which belongs to the family of Field-Effect Transistors (FETs). It has a feature which is not only unique to the 2N6800, but also to all of the FETs: a dual-gate structure, meaning that it has two semi-conductive regions on each side of its channel. This makes the 2N6800 different from the Single-Gate FETs (SG FETs) which have only one semi-conductive region on their gate.

The 2N6800 is most commonly used as an amplifier and in amplifying circuits. It has a low noise factor which makes it ideal for this use. The device works by allowing a small current to flow from the source to its gate when a very small voltage is applied. This current changes the resistance of the gate, which in turn affects the current flowing between the source and the drain. The source to drain current is thus amplified and can be used to drive some external load.

The working principle behind the 2N6800 can be explained by considering the electric field between the two gates, the source and drain. The electric field created by the applied voltage on the two gates is called the “gat-to-drain voltage”. The voltage applied to the gates creates an electric field which drives the majority carriers (electrons in the n-type semiconductor and holes in the p-type semiconductor) through the “channel” formed by the two gates. The electrons and holes, or majority carriers, are then repelled by the drain, allowing the amplified current to flow.

The 2N6800 also has applications in switching circuits. By adjusting the gate-to-drain voltage, the current flowing between the source and the drain can be made changeable, allowing a high-frequency ON/OFF control for a low-noise signal. This feature makes the device ideal for use in switching applications, such as toggling between two different signals.

The 2N6800 is also used as a protection device in automobile circuits, where it prevents electrical fluctuations. The dual-gate structure of the device is also advantageous because it increases the reliability and increases the speed of the device. In addition, the 2N6800 is also used as a level shifter, a kind of voltage regulator, and a common-source amplifying stage.

In summary, the 2N6800 is a dual-gate MOSFET which is most commonly used as an amplifier and in amplifying circuits. It can also be used as a switching device, a protection device, a level shifter, and a common-source amplifying stage. Its dual structure makes it ideal for many applications.
