High-voltage MOSFETs based on MDmesh™

HV Power MOSFETs: The Latest Technologies, Trends & Applications



Watch Now

Get up-to-date on the most recent advances in high-voltage power MOSFET technology and discover which devices are best suited for different target applications.

During this one-hour videp, you will learn about ST’s best-in-class high-voltage MOSFET technology, with emphasis on the super-junction MDmesh™ family. Spanning voltage ratings from 250 V to 1700 V, these discrete devices advance the performance of power topologies from motor control to vehicle electrification, and everything in-between.

Following a review of the devices in ST's broad MDmesh™ portfolio, we'll take a deep dive into the latest 600-700 V M6 series, optimized for high-efficiency switched-mode power supplies (SMPS).

You will learn:

  • What makes the MDmesh™ structure so effective
  • A description of the target applications for each of the 4 MDmesh™ families
  • About the power topologies enabling high efficiency standards
  • The features, benefits, and applications of the M6 series
  • About the diverse packaging options available and related trends
  • How to find resources to help designers with using MDmesh™ MOSFETs

About MDmesh™ Power MOSFETS

  • The Super-Junction MOSFET structure allows to shrink the epitaxial layer of the vertical MOS compared to planar types, reducing Rds(on) for a given die area.
  • There are four modern families of MDmesh devices – M5, M2, M6, and K5 – Spanning drain voltage ratings from 250 V to 1700 V.
  • Each is optimal for differing power applications like CCM PFCs, resonant converters, ZVS bridges, or flybacks.
  • M6 is a new reference for best-in-class performance in resonant topologies.
  • Diverse SMT and through-hole packaging, as well as module options, allow mechanical ease of design in any application.
  • Detailed application notes, selection guides/apps, and models enable quick designs with MDmesh technologies.
