FDD050N03B Description

Short technical summary and product information.

The FDD050N03B is an N-channel power MOSFET manufactured by ON Semiconductor, built using metal-oxide semiconductor (MOSFET) technology. It is designed for applications requiring drain-source voltages up to 30V and continuous drain currents up to 50A at case temperature (Tc).

 

The device features a maximum drain-to-source on-resistance (Rds(on)) of 5 mOhm, measured at a drain current of 25A and 10V gate-to-source voltage. It supports gate drive voltages from 4.5V to 10V, with a maximum gate threshold voltage of 3V at 250uA drain current. The total gate charge is limited to 43 nC at 10V, and input capacitance is 2875 pF at a drain-source voltage of 15V. Power dissipation is rated up to 65W, and the junction temperature range is -55°C to 175°C.

 

The transistor is supplied in a TO-252-3 package (also known as DPAK or SC-63), with a supplier device package designation of TO-252AA. It is intended for surface-mount installation, enabling compact PCB layout and automated manufacturing.

 

With its low on-resistance, high current capacity, and standard DPAK footprint, the FDD050N03B is suitable for power switching, load switching, and DC-DC conversion circuits operating from a 30V rail. The device is a single N-channel MOSFET, appropriate for a wide range of mid-power switching applications.
