The IRF7466 is a trench technology MOSFET, meaning it utilizes a trench gate rather than a planar gate. It is part of a range of MOSFETs currently being produced by International Rectifier. The IRF7466 falls under the category of single MOSFETs specifically.

The IRF7466 is composed of an N-Channel enhancement–mode field-effect transistor (FET) with its control–gate, drain, and source terminals designed to act as a switch. It is specifically designed to have either low or high input impedance, and is able to pass either low or high output current, depending on the attached voltage. When in use as an amplifier, this MOSFET combines both high gain bandwidth and high output currents.

The IRF7466 is typically used in switching mode power supplies, such as those needed for laptops, DVD players, and cell phones. Oftentimes, the IRF7466 will be used in a buck or boost controller to regulate the output voltage of the switching mode power supply. It can also be used in high speed switching applications, such as DC-DC converters. The IRF7466 can be used for DC motor drives, as well as for audio amplifiers.

The working principle of the IRF7466 involves three distinct steps: sourcing, sinking, and simultaneous sourcing and sinking. Sourcing is when the MOSFET acts as a switch between the source and load, allowing the load to receive power from the source. Sinking is when the MOSFET acts as a switch between the load and ground, allowing the load to discharge power. Simultaneous sourcing and sinking is when the MOSFET acts as a switch between the source and ground, allowing the load to receive and discharge power simultaneously.

The IRF7466 can operate at frequencies up to 3 MHz, providing an exceptional degree of control and precision. It has a maximum drain current of up to 0.9A (IDSS) and an avalanche current rating of up to 125A (IAR). The maximum drain-to-source voltage (VDS) is specified at 125V, and the maximum gate-to-source voltage (VGS) is specified at 4V. The on-resistance (RDS(on)) at 1.1V VGS is as low as 0.05ohm, with a total gate charge (Qg) of 0.9nC.

The IRF7466 is a useful, versatile MOSFET that is designed for switching and amplifier applications. Its low on-resistance and total gate charge makes it ideal for high speed switching applications, while its high voltage and current ratings make it ideal for power supply control applications. In addition, its high frequency response makes it useful for accurately controlling motors and audio amplifiers.
