 STW15NK90Z       900 V    < 0.55  15 A 350W

   Extremely high dv/dt capability
   100% avalanche tested
   Gate charge minimized                                               TO-247
   Very low intrinsic capacitances
   Very good manufacturing repeatibility

Description
The SuperMESHTM series is obtained through an
extreme optimization of ST's well established           Internal schematic diagram
strip-based PowerMESHTM 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.
Such series complements ST full range of high
voltage MOSFETs including revolutionary
MDmeshTM products.

Applications
   Switching application
