The FDMS039N08B is a surface-mount N-Channel MOSFET manufactured by onsemi using the advanced POWERTRENCH process. It is designed for applications requiring high efficiency and fast switching, such as synchronous rectification in ATX, server, and telecom power supplies, battery protection circuits, and motor drives.
Key electrical specifications include a drain-source voltage (Vdss) of 80V, continuous drain current of 100A at 25°C case temperature (19.4A at ambient), and a pulsed drain current capability of 400A. The device features a low typical on-resistance of 3.2mΩ and maximum of 3.9mΩ at Vgs=10V and Id=50A. Gate charge is 100nC at 10V, and input capacitance is 7600pF at Vds=40V. The MOSFET is rated for a maximum power dissipation of 104W at case temperature 25°C.
Packaged in an 8-PowerTDFN (8-PQFN 5x6) with a junction-to-case thermal resistance of 1.2°C/W, it is suitable for compact, high-current designs. The device is 100% UIL tested, has a soft reverse recovery body diode, and is RoHS3 compliant, Pb-free, and halide free. Operating junction temperature range is -55°C to 150°C.
