IRFZ24NPBF

The IRFZ24NPBF is a N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by Infineon Technologies. It is designed for high-efficiency power switching applications, making it suitable for a variety of uses in power management, motor control, and other electronic circuits.

Key Features:

1. N-Channel Configuration: The IRFZ24NPBF is an N-channel MOSFET, which means it uses electrons as the charge carriers. This configuration typically offers lower on-resistance and higher efficiency compared to P-channel MOSFETs.

2. Voltage Rating: The device has a maximum drain-source voltage (V_DS) rating of 55V, allowing it to handle a wide range of applications without the risk of breakdown.

3. Current Rating: It can handle a continuous drain current (I_D) of up to 49A at a temperature of 25°C, making it suitable for high-current applications.

4. On-Resistance (R_DS(on)): The IRFZ24NPBF features a low on-resistance, typically around 0.035 ohms at a gate-source voltage (V_GS) of 10V. This low R_DS(on) contributes to reduced power losses and improved thermal performance.

5. Gate Threshold Voltage (V_GS(th)): The gate threshold voltage is specified between 2V and 4V, which indicates the minimum gate voltage required to turn the MOSFET on. This allows for compatibility with various control voltages.

6. Package Type: The IRFZ24NPBF is available in a TO-220 package, which provides good thermal performance and is easy to mount on heatsinks for effective heat dissipation.

7. Thermal Characteristics: The device has a maximum junction temperature (T_J) of 175°C, allowing it to operate in demanding environments. Its thermal resistance from junction to case (RθJC) is low, facilitating efficient heat transfer.

8. Fast Switching Speed: The IRFZ24NPBF is designed for fast switching applications, making it suitable for use in high-frequency circuits.

9. RoHS Compliance: The part is compliant with the Restriction of Hazardous Substances (RoHS) directive, ensuring it is environmentally friendly and free from certain hazardous materials.

Applications:

The IRFZ24NPBF is widely used in various applications, including:

• Power Supplies: It is commonly found in switch-mode power supplies (SMPS) and DC-DC converters due to its efficiency and high current handling capabilities.
