Description
This Power MOSFET is the latest development of
STMicroelectronics unique “single feature size”
strip-based process. The resulting transistor
shows extremely high packing density for low onresistance, moreover the double sides cooling
package with ultra low junction to case thermal
resistance allows to handle higher levels of
current.

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
