STPower logoWith the STPOWER MDmesh M9 series, ST sets a benchmark for the 650V/600V super-junction technology combining best-in-class performance with remarkable ease of use. The innovative high-voltage super-junction STPOWER MDmesh M9 series delivers the best Figure of Merit (RDS(on)max x Qg) on the market as well as an approximately 30% reduction in on-state resistance compared to the previous technology, enabling designers
to increase the power density and obtain more compact system solutions.

 

Applications

Tailored for both hard- and soft-switching topologies, the MDmesh M9 series is ideal for telecom data-centers and servers, 5G power stations and solar microinverters as well as fast chargers, flat-panel displays and PC SMPS.
