NTP75N03RG is an Enhancement Mode Field Effect Transistor (FET) manufactured by ON Semiconductor and is categorized as Single, Non-SI MOSFETs. This high-speed switching device offers an extra-low on-resistance to reduce conduction losses, increase efficiency, and provide better thermal performance.

NTP75N03RG is a robust, reliable n-channel MOSFET which offers high-speed switching characteristics in a small plastic package. When compared to similar devices, it has the advantage of offering a lower on-state resistance. This enables it to be used both as a basic MOSFET switch operating at low and medium frequencies and as a high-performance switch operating up to 500MHz.

Application Field

The NTP75N03RG can be used in a variety of switched-mode power supply (SMPS) applications, such as DC-DC converters, motor drivers, consumer electronics, renewable energy systems, adapters, and hard drives.

This device is well-suited for use in load switching and can be used for a variety of other applications, such as MOSFET drivers, reverse blocking switches, line drivers, and as a pulse width modulation (PWM) switch. Its relatively low on-state resistance and fast switching speed makes it ideal for power management and audio applications.

Working Principle

When in the “off” state, the NTP75N03RG acts as an electrical insulator, blocking the flow of current and allowing no significant voltage to pass through. However, when the gate is biased with a positive voltage, the n-channel MOSFET switches to the “on” state and conducts current. This process allows the MOSFET to be used as an effective switch or as a variable resistor when the gate voltage is adjustable.

When the gate voltage is turned “on”, it attracts the electrons located in the channel of the MOSFET, creating an electron-rich region near the gate. This then creates a current flow between drain and source. When the gate voltage is turned “off”, the electrons are repelled from the gate, removing the current flow.

The NTP75N03RG is robust enough to support utilization in a wide range of temperatures, from -55 to +175 degrees Celsius. It is designed to withstand a maximum source to drain voltage of 30 volts and a drain current of 15 amps, making it a dependable switch for a variety of applications.

Overall, the NTP75N03RG is an effective switch, combining robustness and performance in a small space. It offers a relatively low on-state resistance and fast switching abilities, while also having the advantage of supporting utilization in high temperatures. It can be used in a variety of applications, including motor drives, consumer electronics, voltage converters, and power management circuits.
