November 1995 2N7000 / 2N7002 / NDS7002A N-Channel Enhancement Mode Field Effect Transistor General Description Features High density cell design for low RDS(ON). These N-Channel enhancement mode field effect transistors are produced using Fairchild's proprietary, high cell density, Voltage controlled small signal switch. DMOS technology. These products have been designed to Rugged and reliable. minimize on-state resistance while provide rugged, reliable, and fast switching performance. They can be used in most High saturation current capability. applications requiring up to 400mA DC and can deliver pulsed currents up to 2A. These products are particularly suited for low voltage, low current applications such as small servo motor control, power MOSFET gate drivers, and
