Next-gen MOSFETs boost efficiency and power density for servers and high-performance PCs
Magnachip Semiconductor Corporation has introduced its latest generation of medium-voltage power devices with the launch of 8th-generation 40V and 60V MV MOSFETs, specifically engineered to meet the evolving demands of server infrastructure and high-performance computing (HPC) systems. The announcement underscores the company’s continued focus on advancing power semiconductor technologies that enable higher efficiency, greater power density, and improved reliability in modern computing environments.
The new product lineup was showcased at PCIM Europe 2026 held in Nuremberg, one of the world’s leading exhibitions for power electronics, intelligent motion, renewable energy, and energy management. At the event, Magnachip highlighted how its latest MV MOSFET solutions are designed to address critical challenges faced by data centers and enterprise computing systems, particularly as global demand for computational power continues to surge.
Rising Power Demands in Data Centers
The rapid expansion of cloud computing, artificial intelligence workloads, and data-intensive applications has significantly increased power consumption across servers and data centers. As organizations scale their infrastructure to meet these demands, power efficiency and thermal management have become key design priorities. Inefficient power conversion not only leads to higher operational costs but also creates challenges in maintaining system stability and sustainability.
In this context, power semiconductors—particularly MOSFETs—play a crucial role. These components are integral to power supply units (PSUs), where they regulate voltage, manage current flow, and ensure efficient energy conversion. Any improvement in MOSFET performance can translate directly into better system-level efficiency and reduced energy losses.
Magnachip’s 8th-generation MV MOSFETs are positioned as a response to these evolving requirements. By focusing on both efficiency and reliability, the company aims to provide solutions that can support next-generation server architectures and HPC environments.
Engineering Advancements and Performance Gains
At the core of the new devices is Magnachip’s Advanced Shielded Gate Trench (SGT) technology, which enables significant performance enhancements over previous generations. The 40V MOSFET variants deliver up to a 40% improvement in current density and approximately 25% faster switching speeds. Meanwhile, the 60V variants achieve even greater gains, with up to a 50% increase in current density and a 60% improvement in switching speed.
These improvements are particularly important in high-frequency switching applications, where faster switching reduces energy loss during transitions and enhances overall efficiency. Higher current density, on the other hand, allows more power to be handled within a smaller footprint, supporting compact and high-density designs.
Another notable feature is the integration of fast anti-parallel diode technology. This capability helps dissipate residual current generated during switching events, reducing the risk of inefficiencies and improving overall system stability. In high-performance computing environments, where systems operate under continuous and often heavy loads, such enhancements are critical for maintaining consistent performance.
Role in Synchronous Rectification
The new MOSFETs are specifically designed for use in the synchronous rectification (SR) stage of power supply systems. This stage is responsible for converting alternating current (AC) to direct current (DC) with minimal losses. By replacing traditional diode-based rectification with MOSFET-based solutions, synchronous rectification significantly improves efficiency.
Magnachip’s latest devices enhance this process by minimizing conduction and switching losses, thereby improving the overall efficiency of power supplies used in servers and high-performance PCs. This is especially relevant in hyperscale data centers, where even small efficiency gains can result in substantial cost savings when applied across thousands of servers.
Thermal Performance and Design Flexibility
Thermal management remains a critical concern in power electronics, particularly in densely packed server environments. The new MOSFETs support a wide operating temperature range of up to 175°C, ensuring stable performance even under extreme conditions. This capability allows system designers to operate devices closer to their performance limits without compromising reliability.
In addition, the devices are housed in a compact PDFN56 package, which facilitates high-density board layouts. As server architectures continue to prioritize compactness and scalability, such packaging innovations are essential for optimizing space utilization while maintaining performance.
The MOSFETs are also designed to meet JEDEC standards, ensuring compatibility and reliability across a wide range of applications. While the primary focus is on server and HPC power supplies, these devices are also suitable for use in solar inverters and industrial power systems, where efficiency and durability are equally important.
Expanding the Product Portfolio
The launch builds upon Magnachip’s earlier introduction of a 0.7mΩ 40V MOSFET in 2025. With the addition of new variants—including 0.8mΩ and 1.0mΩ 40V devices, as well as a 1.05mΩ 60V device—the company is expanding its portfolio to offer greater flexibility in voltage and resistance options.
This expanded lineup enables customers to select components that best match their specific performance and design requirements. Lower RDS(on) values, for example, reduce conduction losses and improve efficiency, while different voltage ratings allow for broader application coverage.
Market Outlook and Strategic Positioning
The introduction of these new products comes at a time when the global market for server and data center power supplies is experiencing steady growth. According to industry projections, the market is expected to expand from approximately $2.3 billion in 2025 to $3.0 billion by 2029, reflecting a compound annual growth rate (CAGR) of 7.4%.
This growth is driven by increasing demand for cloud services, AI-driven applications, and edge computing infrastructure. As a result, the need for efficient and reliable power solutions is becoming more pronounced.
By strengthening its MV MOSFET portfolio, Magnachip aims to capture a larger share of this expanding market. The company’s focus on high-value-added power solutions positions it to compete effectively in a sector where performance, efficiency, and reliability are key differentiators.
