ST's 550 V and 650 V MDmesh M5 super-junction high voltage MOSFETs are optimized for high-power PFC and PWM topologies in hard switching applications, such as solar-power converters, power supplies for consumer products, electronic lighting controls and EV/HEV.

Our MDmesh M5 high-voltage MOSFET portfolio enables new generations of energy-conscious, compact and reliable electronic products, thanks to low on-state losses per silicon area combined with low gate charge (Qg) in a wide range of packages. This includes the new 4-lead TO247-4 which features a dedicated control pin for increased switching efficiency, the 1-mm-high surface-mount PowerFLAT 8x8 HV and PowerFLAT 5x6 HV featuring an exposed metal drain pad for efficient heat dissipation. These power MOSFETs are belonging to the STPOWER™ family.

Key features and benefits

  • Extremely low RDS(on) for increased efficiency and more compact designs
  • Optimized trade-off between RDS(on) and capacitance profiles for increased performance in high-power PFC

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