Product Summary

The STW9NK90Z is an N-CHANNEL Zener-Protected SuperMESH Power MOSFET. The STW9NK90Z is obtained through an extreme optimization of ST’s well established stripbased 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. Such series complements ST full range of high voltage MOSFETs including revolutionary MDmesh products. The applications of the STW9NK90Z include high current, high speed switching, switch mode power supplies, DC-AC converters for welding, ups and motor drive.
