The 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, including AEC-Q101-qualified devices for automotive applications, 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, H2PAK-2, TO-LL, PowerFLAT HV (8 x 8 mm) and SOT223-2. These power MOSFETs belong to the STPOWER family.
The first automotive grade device in the STPOWER MDmesh DM9 AG series is the STH60N099DM9-2AG, in H2PAK-2 package.
Applications
Ideal for equipment such as charging stations for electric vehicles, telecom data centers, 5G power stations, servers, solar inverters, UPS, and energy storage systems, on board chargers (OBC) and DC-DC converters for EV/HEV, the MDmesh DM9 series enables superior energy ratings with more robust performance and increased power density.
Product types
The MDmesh DM9 series offers an improved reduction of maximum drain-source on resistance compared to the previous technology (MDmesh DM6 series) by package type (TO-220, TO-LL, PowerFLAT 8x8 HV, and DPAK).
Benefits
- Increased level of power
- Extremely high efficiency and increased power density
- Improved system reliability and robustness
- Higher operating frequencies and better thermal management

With MDmesh M9/DM9 series, ST sets a benchmark for the 600V/650V super-junction technology combining best-in-class performance with remarkable ease of use. Tailored for both hard- and soft-switching topologies, the MDmesh M9 and DM9 series are ideal for data centers, 5G power servers, telecommunications, EV charging and solar applications.
ST offers high-voltage MDmesh M6 & M9 STPOWER MOSFETs in a new compact, thermally efficient package: the TO-LL surface-mounted package offers high electrical and thermal efficiency, compactness and space saving in power conversion applications like SMPS, data centers and solar microinverters. Thanks to the additional Kelvin-source lead, designers can achieve better efficiency due to reduced turn-on/turn-off switching losses.
