~[R1D~LP~ FIELD EFFECT POWER TRANSISTOR IRF642,643 16 AMPERES 200,150 VOLTS ROS(ON) = 0.22 D. This series of N-Channel Enhancement-mode Power MOSFETs utilizes GE's advanced Power DMOS technology to achieve low on-resistance with excellent device ruggedness and reliability. This design has been optimized to give superior performance in most switching applications including: switching power supplies, inverters, converters and solenoid/relay drivers. Also, the extended safe operating area with good linear transfer characteristics makes it well suited for many linear applications such as audio amplifiers and servo motors.
