ST power logoThe state-of-the-art MDmesh DM9 super-junction power MOSFETs are ST's latest fast-recovery diode MOSFET series, optimized for full-bridge phase-shifted ZVS topologies. These 600 and 650 V fast-recovery MOSFETs feature the best Figure of Merit (RDS(on) max x Qg) on the market, a very low recovery charge and time (Qrr, trr) and deliver up to 46% lower RDS(on) compared to the previous generation. The MDmesh DM9 series is available in a wide range of package options including TO-247 long leads, TO-220, TO-LL, PowerFLAT HV (8 x 8 mm) and SOT223-2. These power MOSFETs belong to the STPOWER family.



Ideal for equipment such as charging stations for electric vehicles, telecom data centers, 5G power stations, servers, solar inverters, UPS, and energy storage systems, the MDmesh DM9 series enables superior energy ratings with more robust performance and increased power density.
