Using the well consolidated high voltage MESH
OVERLAY™ process, STMicroelectronics has
designed an advanced family of Power MOSFETs
with outstanding performances. The strengthened
layout coupled with the company’s proprietary
edge termination structure, gives the lowest
R
switching characteristics.

4 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
