| IRFF420 Data Sheet March 1999 File Number 1891.4 1.6A, 500V, 3.000 Ohm, N-Channel Power MOSFET This N-Channel enhancement mode silicon gate power field effect transistor is an advanced power MOSFET 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 TA17405. Features * 1.6A, 500V * rDS(ON) = 3.000 * Single Pulse Avalanche Energy Rated * SOA is Power Dissipation Limited * Nanosecond Switching Speeds * Linear Transfer Characteristics * High Input Impedance * Related Literature - TB334 "Guidelines for Soldering Surface Mount Components to PC Boards" Ordering Information PART NUMBER IRFF420 PACKAGE TO-205AF BRAND IRFF420 Symbol D NOTE: When ordering, include the entire part number.
