March 2026 - Magnachip Semiconductor

– Advanced Shielded-Gate Trench (SGT) Technology Simultaneously Improves Current Density and Switching Speed

– Targeting the Next-Generation Power Supply Market with High-Temperature Reliability and Energy Efficiency Requirements

SEOUL, South Korea, Mar 2026 – Magnachip Semiconductor Corporation (NYSE: MX, “Magnachip”) today announced the launch of its new 8th-generation 40V and 60V Medium-Voltage (MV) MOSFETs, designed for server and high-performance PC power supply units.

As power demand in the global server and data center market increases, power efficiency and power density have emerged as important factors for power semiconductor solutions used in servers and data center applications. With these new 8th-generation MV MOSFETs, Magnachip expands its solution offerings to simultaneously meet customers’ efficiency and reliability requirements in the fast-growing server and high-performance computing (HPC) power supply market, further reinforcing its competitiveness in high-value-added power solutions.

These new products are designed for use in the Synchronous Rectification (SR) stage of server and PC power systems. Incorporating Advanced SGT technology, the 40V products deliver up to 40% improvement in current density and approximately 25% faster switching speed compared to the previous generation, while the 60V products achieve up to 50% improvement in current density and 60% faster switching speed. In addition, fast anti-parallel diode technology is applied to rapidly dissipate residual current generated during switching, which can enhance overall system stability. The devices support a wide operating temperature range of up to 175°C, which enables stable performance even in high-temperature environments, and adopt a compact PDFN56 package to facilitate high-density and compact power designs. Built to meet JEDEC standards, these MOSFETs are designed for use not only in server and high-performance PC power supply units, but also in solar inverters and industrial power systems where high efficiency and reliability are important.

Following the launch of the 0.7mΩ 40V product in May 2025, Magnachip is further strengthening its 8th-generation MV MOSFET portfolio with diverse voltage and R_DS(on)options by introducing three additional products: 0.8mΩ 40V, 1.0mΩ 40V, and 1.05mΩ 60V devices. According to global market research firm Omdia, the global server and data center power supply market (Computing and Data Storage) is projected to grow from approximately $2.3 billion in 2025 to $3.0 billion in 2029, representing a compound annual growth rate (CAGR) of 7.4%. Through this expanded product lineup, Magnachip aims to further strengthen its technological competitiveness and market share in the rapidly growing power semiconductor market.

“These new products are expected to serve as a solution that can enhance both efficiency and reliability in server and high-performance PC power systems,” said Hyuk Woo, Chief Technology Officer of Magnachip. “Leveraging our accumulated power semiconductor design expertise and proven manufacturing capabilities, Magnachip will continue to introduce high-value-added power solutions across server, PC, and industrial applications.”

At PCIM Europe 2026 in Nuremberg, Germany (Hall 6, Booth 337), Magnachip will present its latest MV MOSFET solutions, highlighting their role in enabling high-efficiency and high-density power systems.

– Achieves a 26% reduction in chip size and a 31% improvement in R_ss(on)based on Super-Short Channel FET technology

– Expands battery protection solutions for a wide range of mobile devices.

SEOUL, South Korea— Magnachip Semiconductor Corporation (NYSE: MX, “Magnachip”) today announced the launch of its new 7^th-generation 24V MXT LV MOSFET[1] specifically designed for battery protection circuits in next-generation tri-fold smartphones, strengthening its presence in the premium foldable smartphone market. The product is now in mass production and is currently being supplied to a major global smartphone manufacturer, having demonstrated proven performance and reliability.

The newly introduced 24V Dual N-channel MOSFET (MDWC24D058ERH) incorporates Magnachip’s proprietary Super-Short Channel FET (SSCFET®)[2] technology, reducing chip size by approximately 26% compared to the previous version. This enables manufacturers to reduce the footprint of the battery protection circuit module (PCM) board by more than 20%, allowing the saved space to be used for increased battery capacity or slimmer device designs.

Tri-fold smartphones feature a new form factor that folds twice and operates three displays simultaneously, enabling high-performance multitasking. As a result, their internal structures have become more complex, power-efficient and reliable, while also becoming increasingly critical in design. Accordingly, these devices demand highly integrated and efficient MOSFET solutions to manage complex internal structures while ensuring power stability.

In addition to tri-fold smartphones, the new product can be applied across a wide range of mobile applications, including wearable devices and tablets. It reduces R_SS(on),a major source of power loss, by up to approximately 31%, helping to reduce heat generation. The new product also improves current density per unit area by approximately 48% compared to conventional trench processes, supporting stable voltage control under high-current conditions. In addition, it integrates electrostatic discharge (ESD) protection of more than 2kV, helping to safeguard battery systems from external disturbances.

According to market research firm Omdia, the market for silicon power MOSFETs below 40V, including smartphone batteryFETs, is expected to grow from approximately $4.2 billion in 2025 to approximately $5.2 billion in 2029, representing a compound annual growth rate of about 4.6%. Within this market, the premium smartphone segment, including tri-fold smartphones, is expected to drive growth, supported by increasing demand for high-performance and high-efficiency components.

“Tri-fold smartphones represent high-end mobile devices that require advanced technology and superior component reliability,” said Hyuk Woo, Chief Technology Officer of Magnachip. “Through the supply of this new MOSFET product, we have once again demonstrated Magnachip’s power semiconductor design capabilities and technological competitiveness. Going forward, we will continue to expand our power semiconductor portfolio for a wide range of mobile applications, including smartphones, wearables, and tablets, through ongoing innovation.”
