-25 V, -0.12 A continuous, -0.5 A Peak.
RDS(ON) = 13 @ VGS= -2.7 V
RDS(ON) = 10 @ VGS = -4.5 V.
Very low level gate drive requirements allowing direct
operation in 3V circuits. VGS(th) < 1.5V.
Gate-Source Zener for ESD ruggedness.
>6kV Human Body Model
Compact industry standard SOT-23 surface mount
package.
Replace many PNP digital transistors (DTCx and DCDx)
with one DMOS FET.
This P-Channel logic level enhancement mode field effect
transistor is 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 digital transistors. Since
bias resistors are not required, this one P-channel FET can
replace several digital transistors with different bias resistors
such as the DTCx and DCDx series.
