Working Principle

The working principle of a MOSFET is similar to the operation of a JFET. When a voltage is applied to the gate of the MOSFET, a field is created in the region between the gate and the channel. This field repels the electrons in the channel region, creating a resistance to current flow. The higher the voltage applied to the gate, the lower the resistance and the greater the current flow through the channel. This is the basic operation of the MOSFET.

When the MOSFET is built in the form of a vertical double-diffused MOSFET, the gate is connected to the substrate through an insulated layer of metal oxide. This insulation layer is extremely thin, creating a region of relatively high electric field. This improved design, along with the use of special high-voltage processing techniques, allows the MOSFET to handle high peak currents and achieve very low RDS(on).

The ZVN4310GTC is an ideal choice for applications that require high peak currents and excellent power efficiency. Its low RDS(on) and high voltage rating of 150V make it a great choice for high-voltage power supplies, DC-DC converters, and brushless DC motor controls.
