Product Summary

The STQ1NC45R-AW is a power MOSFET obtained through an extreme optimization of ST’s well established strip-based PowerMES 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 STQ1NC45R-AW is suitable for switch mode low power supplies (smps), low power, low cost cfl (compact fluorescent lamps) and low power battery chargers.
