Part of the STPOWER™ portfolio, the MDmesh M6 series comprises 37 part numbers covering current ratings from 13A to 72A

STMicroelectronics’ MDmesh™ M6 series 600V super-junction transistors are engineered for high efficiency in medium-power resonant and hard-switching converter topologies.

The threshold voltage optimized for soft switching makes the the new transistors ideally suited for LLC resonant converters and boost-PFC converters in energy-conscious applications. MDmesh M6 devices perform efficiently in hard-switching topologies, too, with their capacitance profile enhancing light-load efficiency and gate charge (Qg) as low as 16 nC permitting high switching frequencies.

In addition, ST’s state-of-the-art M6 super-junction technology helps reduce RDS(ON) to as little as 0.036Ω, unleashing extra efficiency gains and increasing power density in equipment such as battery chargers, power adapters, PC power supplies, LED-lighting drivers, telecom and server power supplies, and solar micro-inverters.

Package options include the space-saving and thermally efficient new leadless TO-LL, as well as popular through-hole and surface-mount packages including DPAK, D2PAK, TO-220, TO-247, and PowerFLAT™. The JEDEC-registered TO-LL power-package outline has 30% smaller footprint and 50% lower height than the established D²PAK 7-pin, allowing more compact and space-efficient power converters. With low parasitic inductances, TO-LL also helps minimize electromagnetic interference.

Key Features

  • Reduced RDS(ON) to as little as 0.036Ω, unleashing extra efficiency gains and increasing power density.
  • Threshold voltage optimized for soft switching.
