FQA7N80C

FQA7N80C Application Field and Working Principle

FQA7N80C is a type of field effect transistor (FET). It belongs to the family of single-gate MOSFETs, where the gate is isolated from the drains and source electrodes by an oxide barrier. The FQA7N80C is widely used in microelectronic devices, and is especially suited for power management applications in notebooks, tablet PCs and other handheld mobile devices.

Basic Working Principle

The FQA7N80C works on the principle of electron charge decoupling between the source-drain electrodes and the gate electrode. When a voltage is applied to the gate electrode, it creates an electrical field around it. This field forms an independant layer between the source and drain electrodes, which prevents any current leakage between them. This layer is called the depletion layer, and it behaves as an insulator between these electrodes.

By controlling the voltage applied to the gate electrode, the depletion layer can be adjusted or relaxed. When the depletion layer is relaxed, it allows electrons to flow from the source to the drain, creating an on-state in the FET and allowing current to flow from the source to the drain. Conversely, when the depletion layer is tightened, it impedes the flow of electrons from the source to the drain, creating an off-state in the FET and preventing current from flowing from the source to the drain. This is the basic working principle of the FQA7N80C.
