The NTA4001NT1G is a N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by ON Semiconductor. This device is designed for various applications, including power management, switching, and amplification in electronic circuits.

Key Features:

1. Type: N-channel MOSFET

   • The NTA4001NT1G is specifically designed to conduct current when a positive voltage is applied to the gate terminal relative to the source terminal.

2. Voltage Rating:

   • The maximum drain-source voltage (V_DS) is typically rated at 30V, making it suitable for low to moderate voltage applications.

3. Current Rating:

   • The device can handle a continuous drain current (I_D) of up to 4.5A, which allows it to drive moderate loads effectively.

4. R_DS(on):

   • The on-resistance (R_DS(on)) is low, typically around 0.045 ohms at a gate-source voltage (V_GS) of 10V. This low resistance minimizes power loss during operation, enhancing efficiency.

5. Gate Threshold Voltage (V_GS(th)):
