- New Package Lineup Targets Premium Consumer Electronics and High-Power/High-Current Markets

- Additional SJ MOSFET TOLL products are planned to be released for AI Data Centers

SEOUL, South Korea--(BUSINESS WIRE)--Oct. 29, 2025-- Magnachip Semiconductor Corporation (NYSE: MX, “Magnachip”) today announced the release of two new 650V Super Junction MOSFET (SJ MOSFET) products, adopting the TO-Leadless (TOLL) package, that are designed to meet the high-power and high-current requirements of premium consumer electronics such as premium TVs, gaming monitors, AI laptop adaptors, and chargers.

Magnachip Launches 650V Super Junction TOLL Package Products with Integrated Kelvin Source

Current Magnachip products with TOLL packaging, such as the 80V – 200V eXtreme Trench MOSFETs, use a 3-pin configuration. The new 650V SJ MOSFETs have a 4-pin Kelvin configuration, which minimizes the effects of parasitic inductance on the gate-source return path, thereby improving switching stability and overall power efficiency by reducing gate oscillation (Ringing).

As compared to a conventional D²PAK package, the 4-pin TOLL package delivers more than a 100% increase in current capability, a 24% reduction in footprint and a 48% reduction in height. Therefore, the 4-pin TOLL package is suitable for smaller PCB and high-power density applications, which demand high power efficiency and effective heat dissipation performance.

Hyuk Woo, CTO of Magnachip, commented: “Our new 650V SJ MOSFET TOLL products are designed to meet both PCB space-saving and high-performance requirements of slim form-factor applications. Magnachip will continue to expand its 600V TOLL package product lineup in the near future to support new-generation products for AI datacenters and high-power applications.”
