2 May 998 NT55 N-Channel Enhancement Mode Field Effect Transistor General escription These N-Channel enhancement mode power field effect transistors are produced using Fairchild's proprietary, high cell density, MOS technology. This very high density process is especially tailored to minimize on-state resistance and provide superior switching performance. These devices are particularly suited for low voltage applications such as C motor control and C/C conversion where fast switching, low in-line power loss, and resistance to transients are needed. Features 4 A, 6 V. R S(ON) =. V GS = V. High density cell design for extremely low R S(ON). High power and current handling capability in a widely used surface mount package.
