The FDD8445 is an N-Channel MOSFET from On Semiconductor, designed for power switching applications. It features a drain-source voltage (Vdss) of 40V and a continuous drain current (Id) of 70A. The device offers a low on-resistance of 8.7mOhm maximum at 50A and 10V gate drive, ensuring efficient power conversion.
The MOSFET has a gate charge of 59nC at 10V and an input capacitance of 4050pF at 25V, making it suitable for moderate-speed switching. The threshold voltage is 4V maximum at 250µA, and the gate-source voltage is rated at ±20V. Maximum power dissipation is 79W at case temperature, and the junction operates from -55°C to 175°C.
This device is offered in a surface-mount TO-252-3 (DPak) package, also known as SC-63, with the supplier device package TO-252AA. It is intended for use in DC-DC converters, load switches, and other power management circuits.
