NDS9945

May 1998 NDS9945 Dual N-Channel Enhancement Mode Field Effect Transistor General Description SO-8 N-Channel enhancement mode power field effect transistors are produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density process is especially tailored to provide superior switching performance and minimize on-state resistance. These devices are particularly suited for low voltage applications such as disk drive motor control, battery powered circuits where fast switching, low in-line power loss, and resistance to transients are needed. Features 3.5 A, 60 V. RDS(ON) = 0.100 Ω @ VGS = 10 V, RDS(ON) = 0.200 Ω @ VGS = 4.5 V. High density cell design for extremely low RDS(ON). High power and current handling capability in a widely used surface mount package. Dual MOSFET in surface mount package.
