FDP8440 Description

Short technical summary and product information.

The FDP8440 is an N-Channel MOSFET designed for high-current switching applications. It features a drain-source voltage rating of 40V and a continuous drain current of 100A (package limited) or 277A (silicon limited) at Tc=25°C. The device offers low on-resistance: 2.2 mΩ maximum at Vgs=10V and 2.4 mΩ maximum at Vgs=4.5V, ensuring efficient power conversion. Gate charge is 450 nC maximum, with low Miller charge (74 nC typical) for fast switching. Input capacitance is 24740 pF maximum. Switching times include turn-on delay 95 ns max, rise time 275 ns max, turn-off delay 875 ns max, and fall time 590 ns max. The MOSFET is rated for single-pulse avalanche energy of 1682 mJ. It is housed in a TO-220-3 through-hole package and operates over a junction temperature range of -55°C to 175°C. Typical applications include power tools, synchronous rectification, battery protection circuits, motor drives, and uninterruptible power supplies.
