Working Principle of FDI33N25TU

The FDI33N25TU is based on the Metal Oxide Semiconductor Field Effect Transistor (MOSFET) technology. It is built from two structures of polysilicon layers. The first structure is called the gate, which is grounded to the source and is the control element of the transistor. The second structure is the body and is what forms the channel between the source and drain. The channel is formed by a special dielectric material between the body and the gate.

The FDI33N25TU works on a basic principle of field effect transistors. The voltage applied to the gate is used to create an electric field between the gate and the body. This electric field is used to alter the conductivity of the channel. As the voltage on the gate is increased or decreased, the amount of current flowing through the channel is also increased or decreased respectively.
