The NTTFS4840NTAG is a single N-Channel MOSFET designed for various applications including DC-DC converters, point of load, power load switches, notebook battery management, and motor control. It features a maximum drain-to-source voltage of 30 V and a continuous drain current rating of 26 A at a junction temperature of 25¬8C. The device has a low on-resistance (RDS(on)) of 24 mOc at 10 V and 20 A, which helps minimize conduction losses. The MOSFET is characterized by low gate charge and capacitance, optimizing switching performance and reducing driver losses. It operates within a temperature range of -55¬8C to +150¬8C and is compliant with RoHS standards, being both Pb-free and halogen-free. The package type is WDFN8, suitable for surface mounting, and it is available in tape and reel packaging for efficient handling. Engineers considering this component should note its thermal resistance ratings, with a junction-to-case thermal resistance of 4.5¬8C/W and a junction-to-ambient thermal resistance of 57.5¬8C/W under steady-state conditions. The device is suitable for applications requiring efficient power management and thermal performance.
