NDS355N
N-Channel Logic Level Enhancement Mode Field Effect Transistor
General Description Features
March 1996
These N-Channel logic level 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 minimize on-state resistance.
These devices are particularly suited for low voltage
applications in notebook computers, portable phones, PCMICA
cards, and other battery powered circuits where fast switching,
and low in-line power loss are needed in a very small outline
surface mount package.
1.6A, 30V. R
= 0.125Ω @ VGS = 4.5V.
DS(ON)
Proprietary package design using copper lead frame for
superior thermal and electrical capabilities.
High density cell design for extremely low R
DS(ON)
.
Exceptional on-resistance and maximum DC current
capability.
Compact industry standard SOT-23 surface mount
package.
