FDMS3572

The FDMS3572 is a dual N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by ON Semiconductor. It is designed for high-efficiency power management applications, including DC-DC converters, load switching, and other power-related functions.

Key Features:

1. Configuration: The FDMS3572 features a dual configuration, meaning it contains two N-channel MOSFETs in a single package. This allows for compact designs and efficient use of board space.

2. Package Type: It is typically available in a compact SO-8 (Small Outline) package, which is surface-mountable. This package type is advantageous for automated assembly processes and helps in reducing the overall footprint on the PCB.

3. Voltage Rating: The FDMS3572 has a maximum drain-source voltage (V_DS) rating of around 30V, making it suitable for a variety of low to medium voltage applications.

4. Current Rating: The device can handle continuous drain currents (I_D) of up to 20A, depending on the thermal conditions and PCB layout. This high current capability makes it suitable for applications requiring significant power handling.

5. R_DS(on): One of the critical specifications of the FDMS3572 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 on-resistance contributes to reduced conduction losses, enhancing overall efficiency.

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

7. Thermal Performance: The FDMS3572 is designed to operate efficiently at elevated temperatures, with a maximum junction temperature (T_J) rating of 150°C. This makes it suitable for applications where heat dissipation is a concern.

8. Applications: Common applications for the FDMS3572 include:

   • Power management circuits
   • DC-DC converters
   • Load switches
   • Motor drivers
   • Battery management systems

9. Reliability: The device is built to meet stringent reliability standards, making it suitable for automotive and industrial applications where long-term performance is critical.

Summary:

The FDMS3572 from ON Semiconductor is a versatile and efficient dual N-channel MOSFET that offers low on-resistance, high current handling, and compact packaging. Its specifications make it an excellent choice for a wide range of power management applications, ensuring reliable performance in demanding environments.
