IRF640, RF1S640, RF1S640SM Data Sheet January 2002 18A, 200V, 0.180 Ohm, N-Channel Power MOSFETs These are N-Channel enhancement mode silicon gate power field effect transistors. They are advanced power MOSFETs designed, tested, and guaranteed to withstand a specified level of energy in the breakdown avalanche mode of operation. All of these power MOSFETs are designed for applications such as switching regulators, switching convertors, motor drivers, relay drivers, and drivers for high power bipolar switching transistors requiring high speed and low gate drive power. These types can be operated directly from integrated circuits. Formerly developmental type TA17422. Features • 18A, 200V • rDS(ON) = 0.180Ω • Single Pulse Avalanche Energy Rated • SOA is Power Dissipation Limited • Nanosecond Switching Speed • Linear Transfer Characteristics • High Input Impedance • Related Literature – TB334 “Guidelines for Soldering Surface Mount Components to PC Boards” Ordering [ … ]
