Fairchild Semiconductor's FDP8443 is a high-performance N-Channel PowerTrench® MOSFET designed for demanding applications. This component offers a Drain-to-Source Voltage (Vdss) of 40V and a continuous drain current capability of 20A at ambient temperature (Ta) and 80A at case temperature (Tc). With a maximum power dissipation of 188W (Tc), it is suitable for high-power switching and power management tasks. The device features a low on-resistance of 3.5mOhm at 80A and 10V, minimizing conduction losses. Its TO-220-3 through-hole package facilitates robust mounting and thermal management. Key electrical parameters include a gate charge (Qg) of 185 nC at 10V and input capacitance (Ciss) of 9310 pF at 25V. Operating across a wide temperature range of -55°C to 175°C (TJ), the FDP8443 finds application in power supplies, motor control, and battery management systems.
