The FDN337N is a specific part number from the Fairchild (now ON Semiconductor) N-Channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) series. MOSFETs are widely used in electronic circuits for switching and amplification purposes.
Here are some key specifications of the FDN337N MOSFET:
1. Type: It is an N-Channel MOSFET, which means it conducts current when a positive voltage is applied between its drain and source terminals.
2. Voltage Rating: The FDN337N has a drain-source voltage rating of 20 volts (VDS), indicating the maximum voltage it can withstand when the device is fully off.
3. Current Rating: It has a continuous drain current rating of 3.6 amperes (ID), which represents the maximum current that can flow through the MOSFET when fully turned on.
4. Low On-Resistance: The FDN337N offers a low on-resistance of typically 50 milliohms (RDS(on)), which helps reduce power dissipation and improve efficiency in switching applications.
5. Package Type: The "N" in the part number indicates the package type, which is an SOT-23 (Surface-Mounted Device Outline 23) package. It is a small and commonly used package for SMD components.
The FDN337N MOSFET can be utilized in various applications, including power management, battery protection, load switches, and other circuitry where low on-resistance and high current-handling capability are required.
