N-Channel Logic Level Enhancement Mode Field Effect Transistor
General Description
Features
TM
SuperSOT -3 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, PCMCIA 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.

SOT-23
2.2 A, 30 V, RDS(ON) = 0.065 Ω @ VGS = 4.5 V
RDS(ON) = 0.082 Ω @ VGS = 2.5 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.

Note:
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.
Typical RθJA using the board layouts shown below on FR-4 PCB in a still air environment :
