FDC6321C
Dual N & P Channel , Digital FET
General Description Features
These dual N & P Channel logic level enhancement mode N-Ch 25 V, 0.68 A, RDS(ON) = 0.45 @ VGS= 4.5 V
field effect transistors are produced using Fairchild's
proprietary, high cell density, DMOS technology. This very P-Ch -25 V, -0.46 A, RDS(ON) = 1.1 @ VGS= -4.5 V.
high density process is especially tailored to minimize
on-state resistance. This device has been designed Very low level gate drive requirements allowing direct
especially for low voltage applications as a replacement for operation in 3 V circuits. VGS(th) < 1.0V.
