STW12NK95Z 950 V < 0.90Ω 10 A 230W
■ Gate charge minimized
■ 100% avalanche tested
■ Extremely high dv/dt capability
Description
The SuperMESH™ series is obtained through an
extreme optimization of ST’s well established
strip-based PowerMESH™ layout. In addition to
pushing on-resistance significantly down, special
care is taken to ensure a very good dv/dt
capability for the most demanding applications.

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
