The Vishay IRFU420PBF is an N-channel MOSFET designed for discrete semiconductor applications. The MOSFET has a drain-source breakdown voltage of 500V, and a continuous drain current of 2.4A (Tc) @ 25°C. The MOSFET is packaged in a TO-251AA case/package, and is supplied in tube/rail packaging. The maximum power dissipation is 2.5W (Ta), and 42W (Tc). The MOSFET has a drive voltage of 10V (max Rds On, Min Rds On). The gate-source threshold voltage is 4V @ 250μA, and the maximum gate-source voltage is ±20V. The MOSFET has a maximum Rds On @ Id,Vgs of 3 Ohm @ 1.4A, 10V. The IRFU420PBF is an active product and is currently in production.
