MDmesh M6 series super-junction transistors from STMicroelectronics (ST) are in stock at Mouser Electronics. Designed for high efficiency in medium-power resonant and hard-switching converter topologies, the MOSFETs enable increased power density in equipment such as battery chargers, power adapters, PC power supplies, LED drivers, telecom and server power supplies, and solar micro-inverters.

The series offers gate charges (Qg) as low as 18 nanocoulombs (nC), with an optimised capacitance profile to target high efficiency on new topologies in power conversion applications.

ST’s M6 super-junction technology helps reduce RDS(ON) to as little as 0.036 Ohms, enabling additional efficiency gains.

Offering current ratings from 8A to 72A and breakdown voltages ranging from 600V to 700V, the MOSFETs’ threshold voltage is optimised for soft switching, making them ideal for LLC resonant converters and boost-PFC converters.

The ST MDmesh M6 series MOSFETs are available in a wide range of packaging options, including a TO-Leadless (TO-LL) package solution that enables efficient thermal management in a 30-percent smaller footprint compared to other packages.
