The 2N6800U is a three-terminal N-channel depletion-mode MOSFET whose drain current and drain-to-source voltage (VDS) is controlled by the gate-to-source voltage (VGS). It is a versatile, robust and reliable device designed for low-power switching and linear amplification applications. It is suitable for both digital and analog applications.

Applications of the 2N6800U are varied, ranging from switching circuits and power amplifiers to digital logic and linear applications. As an N-channel device, it is capable of switching higher loads relative to P-channel devices. This makes it particularly useful in low-level driving applications, such as in signal transmission, control, and interfacing. It can also be used as a power amplifier for signal amplification and filtering.

The working principle of the 2N6800U device is based on a depletion-mode MOSFET (MOFSET) device, which is composed of a thin-film layer of metal gate oxide, a gate region, and a source and drain. The thin-film layer of metal gate oxide serves as an insulating layer, preventing current from flowing through the device. This is known as the Gate Oxide Effect.

The gate region is the active region of the device, where the MOSFET can be configured to operate as either an N-channel or P-channel device. In the N-channel configuration, the gate voltage is controlled by the gate-to-source voltage (VGS). The current that flows through the device is affected by the magnitude of the VGS. By setting the VGS to the right value, the current is gated, allowing the user to control the amount of current flowing through the device.

In the P-channel configuration, the drain-to-source voltage (VDS) is controlled by a positive gate voltage. By adjusting this voltage, the current can be gated, allowing for switching and amplification applications. The device also features intrinsic drain-to-source protection, with a built-in clamping diode that protects the device from overvoltage.

The 2N6800U is the perfect choice for low-power switching and linear amplification applications. It is designed with a lower power dissipation than other comparable MOSFET devices. Its robust and reliable design make it suitable for both digital and analog applications, allowing for flexibility and versatility. The 2N6800U\'s working principle and application field are a testament to its quality as a device.
