AO6404

The AO6404 is a dual N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by Alpha & Omega Semiconductor. It is designed for high-efficiency power management applications, making it suitable for a variety of uses in power supplies, DC-DC converters, and other electronic circuits.

Key Features:

1. Structure: The AO6404 features a dual configuration, meaning it contains two N-channel MOSFETs in a single package. This design allows for space-saving in circuit layouts and simplifies the design process for engineers.

2. Voltage Rating: The device typically has a maximum drain-source voltage (V_DS) rating of around 40V, making it suitable for applications that require moderate voltage handling.

3. Current Rating: The AO6404 can handle continuous drain currents of up to 30A, depending on the thermal management and conditions of use. This high current capability is essential for applications that demand robust performance.

4. R_DS(on): One of the critical specifications of the AO6404 is its low on-resistance (R_DS(on)), which is typically around 10 mΩ at a gate-source voltage (V_GS) of 10V. This low resistance minimizes power losses during operation, enhancing overall efficiency.

5. Gate Threshold Voltage: The gate threshold voltage (V_GS(th)) is typically in the range of 1V to 2.5V, allowing for easy drive with standard logic levels.

6. Package Type: The AO6404 is available in a compact SO-8 package, which is a surface-mount package that facilitates easy integration into printed circuit boards (PCBs) while providing good thermal performance.

7. Thermal Characteristics: The device is designed to operate efficiently at elevated temperatures, with a maximum junction temperature (T_J) rating of 150°C. This makes it suitable for high-temperature environments.

8. Applications: The AO6404 is commonly used in applications such as:

   • Power management circuits
   • Synchronous rectification
   • Motor drives
   • Battery management systems
   • LED drivers

Performance Characteristics:

• Switching Speed: The AO6404 is designed for fast switching applications, which is crucial for minimizing switching losses in high-frequency operations.
• Thermal Resistance: The thermal resistance from junction to ambient (RθJA) is optimized to ensure that the device can dissipate heat effectively, which is vital for maintaining performance and reliability.

Conclusion:

The AO6404 from Alpha & Omega Semiconductor is a versatile and efficient dual N-channel MOSFET that meets the demands of modern power electronics.
