Magnachip Semiconductor announced two 650V Super Junction MOSFET products in a TO-Leadless (TOLL) package engineered for high-power, high-current consumer applications, including premium TVs, gaming monitors, AI laptop adaptors, and fast chargers.
Unlike Magnachip’s existing 80V–200V eXtreme Trench MOSFETs in 3-pin TOLL, the new 650V SJ MOSFETs adopt a 4-pin Kelvin configuration. By separating the gate-source return path, the design reduces parasitic inductance, helping to curb gate ringing, improve switching stability, and raise overall power efficiency—especially at higher dv/dt and di/dt.
Against conventional D2PAK packaging, the 4-pin TOLL format delivers more than a 100% increase in current capability, a 24% reduction in board footprint, and a 48% reduction in height. The result is a compact, thermally efficient package well suited to smaller PCBs and high-power-density products that demand strong heat dissipation.
The new devices are aimed at meeting the dual requirements of space savings and performance in slim form-factor systems. The company plans to broaden its 600V TOLL lineup to support next-generation platforms in AI datacenters and other high-power applications.
