N-Channel Logic Level PowerTrenchTM MOSFET
General Description
Features
This N-Channel Logic Level MOSFET is produced
using
Fairchild
Semiconductor's
advanced
PowerTrench process that has been especially tailored
to minimize on-state resistance and yet maintain
superior switching performance.
These devices are well suited for low voltage and
battery powered applications where low in-line power
loss and fast switching are required.
SuperSOTTM -8
SuperSOTTM -6
SOT-23
2.7 A, 30 V. RDS(ON) = 0.046 Ω @ VGS = 10 V
RDS(ON) = 0.060 Ω @ VGS = 4.5 V.
Very fast switching.
Low gate charge (5nC typical).
High power version of industry standard SOT-23
package. Identical pin out to SOT-23 with 30% higher
power handling 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 :
a. 250oC/W when mounted on
a 0.02 in2 pad of 2oz Cu.
b. 270oC/W when mounted on
a minimum pad.
Scale 1 : 1 on letter size paper
2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%.
