The FDS8449 is an N-Channel MOSFET manufactured by On Semiconductor using the advanced POWERTRENCH process. It offers a maximum drain-source voltage of 40V and a continuous drain current of 7.6A at 25°C. The device features a low on-resistance of 29 mΩ at VGS=10V and 36 mΩ at VGS=4.5V, enabling efficient power switching.
With a total gate charge of 11 nC and input capacitance of 760 pF, the FDS8449 is suitable for high-frequency switching applications. It is designed for surface-mount assembly in the widely used 8-SOIC package, supporting compact PCB layouts. The operating junction temperature range is -55°C to 150°C, making it suitable for demanding environments.
The device is Pb-Free, Halide Free, and RoHS compliant, with tape and reel packaging available for automated manufacturing. Typical applications include power management circuits, DC-DC converters, and load switches.
The maximum drain-source voltage (Vdss) is 40V.
The continuous drain current is 7.6A at Ta=25°C.
