FDG6301N
Dual N-Channel, Digital FET

General Description Features

These dual N-Channel logic level enhancement mode
field effect transistors are produced using Fairchild's
proprietary, high cell density, DMOS technology. This
very high density process is especially tailored to
minimize on-state resistance. This device has been
designed especially for low voltage applications as a
replacement for bipolar digital transistors and small

signal MOSFETs.
