STS15N4LLF3
N-channel 40V - 0.0042 - 15A - SO-8
STripFETTM Power MOSFET
General features
Type VDSS RDS(on) ID
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.
