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 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.
The Key Applications of the ST MDmesh M6 devices include:
STMicroelectronics‘ 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
- 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.
Part of the STPOWER portfolio, the MDmesh M6 series comprises 37 part numbers covering current ratings from 13A to 72A and is in production now.
