The IRF7842TR is an N-Channel power MOSFET manufactured by Infineon Technologies, using advanced MOSFET (Metal Oxide) technology. It features a drain-to-source voltage (Vdss) of 40V and a continuous drain current of 18A at 25°C (14A at 70°C). The device offers a very low on-resistance of 5mΩ maximum at 10V gate drive (4.0mΩ typical), and 5.9mΩ maximum at 4.5V gate drive (4.7mΩ typical). Gate charge is 33nC typical (50nC maximum), and input capacitance is 4500pF maximum at 20V drain-source voltage.
The MOSFET is designed for synchronous rectification applications, including synchronous MOSFET for notebook processor power, secondary synchronous rectification for isolated DC-DC converters, and synchronous FET for non-isolated DC-DC converters. It is fully characterized for avalanche voltage and current.
The device is housed in an 8-SOIC (0.154", 3.90mm Width) surface mount package with a supplier device package of 8-SO. It is available in two packaging forms: tube/bulk (standard pack quantity 95) and tape and reel (standard pack quantity 4000). The operating junction temperature range is -55°C to 150°C. Maximum power dissipation is 2.5W at 25°C ambient. The part is lead-free, indicated by the PbF suffix in the part number (IRF7842PbF).
