Product Summary

The STW18NK80Z zener-protected super mesh power mosfet. The STW18NK80Z is obtained through an extreme optimization of ST well established strip-based PowerMESH layout. In addition to pushing on-resistance significantly down, specialcare of the STW18NK80Z is taken to ensure a very good dv/dt capavility for the most demanding applications. Applications of the STW18NK80Z include: high current, high speed switching, ideal for off-line power supplies.
