IRF520PBF

The IRF520PBF is a N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by Vishay, designed for high-speed switching applications. It is commonly used in power management, motor control, and other electronic circuits where efficient switching is required.

Key Features:

1. Type: N-channel MOSFET
2. Package: Typically available in a TO-220 package, which provides good thermal performance and is suitable for heat dissipation.
3. Voltage Rating: The IRF520PBF has a maximum drain-source voltage (V_DS) of 100V, making it suitable for applications that require handling high voltages.
4. Current Rating: It can handle a continuous drain current (I_D) of up to 9.2A at a case temperature of 25°C, which allows it to drive moderate loads effectively.
5. Gate Threshold Voltage (V_GS(th)): The gate threshold voltage ranges from 2V to 4V, indicating the minimum gate-source voltage required to turn the MOSFET on.
6. R_DS(on): The on-resistance (R_DS(on)) is typically around 0.27 ohms at a gate-source voltage of 10V, which contributes to lower power losses during operation.
7. Switching Speed: The IRF520PBF is designed for fast switching, making it suitable for applications that require rapid on/off control.
8. Thermal Resistance: The thermal resistance from junction to case (RθJC) is low, allowing for efficient heat dissipation and enabling the device to operate at higher power levels without overheating.
