STPOWER MDmesh M9 and DM9 series combine best-in-class performance with remarkable ease of use

The 600/650V superjunction power MOSFET technology is the world's only technology suitable for both hard (PFC) and soft switching (LLC), the 600/650V MDmesh M9 series allows more compact solutions and increased power density. The fast intrinsic diode MDmesh DM9 series provides higher dv/dt and di/dt, resulting in increased ruggedness and reliability. With the best figure of merit on the market and up to 46% lower RDS(on) compared to the previous generation these superjunction power MOSFETs help designers to achieve higher system efficiency, increase power density, and optimize thermal dissipation.

The new MDmesh M9 and MDmesh DM9 flyers provide a complete overview of the key features and related benefits of these STPOWER superjunction series.

The test and analysis section shows a comparative benchmark with the previous technology generation and the best competitors, highlighting the excellent performance of these new series in terms of power efficiency.
