Description
d
o
r
This series of devices is realized with the second
generation of MDmesh™ technology. This
revolutionary Power MOSFET associates a new
vertical structure to the company’s strip layout to
yield one of the world’s lowest on-resistance and
gate charge. It is therefore suitable for the most
demanding high efficiency converters.

Package mechanical data
In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a Lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com
