STMicroelectronics MDmesh M6 series super-junction transistors

Click2Contact

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

The threshold voltage optimised for soft switching makes the transistors suitable for LLC resonant converters and boost-PFC converters in energy-conscious applications. The 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.

ST’s 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 leadless TO-LL, as well as 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, enabling more compact and space-efficient power converters. With low parasitic inductances, TO-LL also helps minimise electromagnetic interference.
