ST's MDmesh™ K5 MOSFET series, currently the only very high voltage super-junction technology in the market, ensures the best efficiency and safety margin in the marketplace for SMPS (i.e. metering, weldings, flat panel televisions), lighting (i.e. LED drivers, HID ballasts), solar inverters, factory automation (i.e. industrial drives). Power MOSFETs are belonging to the STPOWER™ family.

These very high voltage power MOSFETs enable designers to meet increasingly strict limits on maximum power consumption and minimum energy efficiency specified by eco-design standards such as Energy Star and the EU’s energy-related products (ErP) directive. They are available at 800 V, 900 V, 950 V, 1050 V, 1200 V, 1500 V and 1700 V.

Key Features

  • Extremely good RDS(on) at very high BVDSS
  • High switching speed
  • 800-1700 V BVDSS rated
  • Fully developed using ST's proprietary MDmesh K5 super-junction technology

Key Benefits

  • High efficiency with lower design complexity
  • Especially targeted for flyback LED driver topologies

Our wide STPOWER™ product portfolio combined with state-of-the art packaging and protections for high reliability and safety helps designers find the right solutions for customized, high-efficiency applications that will last a long lifetime.
