Features

The AO3402 is a N-channel MOSFET designed for efficient switching applications. Key features include:
1. Voltage Rating: It typically has a maximum drain-source voltage (V_DS) of 30V, making it suitable for low-voltage applications.
2. Current Rating: The device can handle continuous drain current (I_D) of up to 30A, depending on the thermal management and conditions.
3. R_DS(on): It offers a low on-state resistance, typically around 10 mΩ, which minimizes power loss and heat generation during operation.
4. Gate Threshold Voltage: The gate-source threshold voltage (V_GS(th)) is low, typically between 1V to 2V, allowing for efficient drive with low gate voltages.
5. Package Options: Available in various packages such as TO-220 and SMD formats, facilitating versatile applications in different designs.
6. Fast Switching Speed: The AO3402 supports high-frequency operation, making it suitable for applications like DC-DC converters and motor drivers.
These features make the AO3402 a reliable choice for power management in consumer electronics, automotive, and industrial applications.
