   STS15N4LLF3     40V     <0.005         15A

   Optimal RDS(on)x Qg trade-off @ 4.5V
   Conduction losses reduced
   Switching losses reduced
                                                                       SO-8
Description
This N-channel enhancement mode Power
MOSFET is the latest refinement of
STMicroelectronic unique "Single Feature SizeTM"
strip-based process with less critical aligment
steps and therefore a remarkable manufacturing
reproducibility. The resulting transistor shows        Internal schematic diagram
extremely high packing density for low on-
resistance, rugged avalanche characteristics and
low gate charge.

Applications
   Switching application
