The Infineon Technologies IRFU4104PBF is an N-channel MOSFET transistor designed for use in power management applications. It has a maximum power dissipation of 140W and a drain-source breakdown voltage of 40V. The continuous drain current @ 25°C is 42A, and the gate-source threshold voltage is 4V @ 250μA. The maximum gate charge is 89nC @ 10V, and the maximum input capacitance is 2950pF @ 25V. The maximum Rds On @ Id,Vgs is 5.5 mOhm @ 42A, 10V. The transistor is mounted on an IPAK (TO-251) package and is suitable for through-hole mounting. It operates in a temperature range of -55°C to 175°C (TJ). The IRFU4104PBF is obsolete (EOL) and has a medium popularity in the market., and the supply and demand status is balanced.
