NDS355AN
N-Channel Logic Level Enhancement Mode Field Effect Transistor
Features
General Description
SuperSOTTM-3
N-Channel
logic
level
enhancement
mode power field effect transistors are produced using ON
Semiconductor'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, PCMCIA cards, and
other
battery powered circuits where fast switching, and low inline power loss are needed in a very small outline surface
mount package.
1.7A, 30 V, RDS(ON) = 0.125 Ω @ VGS = 4.5 V
RDS(ON) = 0.085 Ω @ VGS = 10 V.
Industry standard outline SOT-23 surface mount package
using proprietary SuperSOTTM-3 design for superior
thermal and electrical capabilities.
High density cell design for extremely low RDS(ON).
Exceptional on-resistance and maximum DC current
capability.
Compact industry standard SOT-23 surface mount
package.

Notes:
1. RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RθJC is guaranteed by
design while RθCA is determined by the user's board design.
