Key Terms
shielded-gate trenchtechnical
A shielded-gate trench is a type of internal structure used in power semiconductor chips where the control electrode is placed in a narrow, vertical groove and partially covered by a conductive shield to reduce unwanted electrical interactions. Think of it like lining a drainpipe with an insulated sleeve so only the intended flow is affected; this design lowers energy loss and heat during switching. For investors, it matters because devices using this layout tend to run more efficiently, support smaller and cooler power supplies, and can give product lines an advantage in markets for electric vehicles, data centers, and power electronics.
mosfettechnical
A MOSFET is a tiny electronic switch used to control the flow of electricity in chips and circuits, functioning like a faucet that turns current on or off and adjusts how much passes through. Investors watch MOSFETs because their performance, cost and availability affect product power efficiency, manufacturing yields and supply chains for industries from consumer electronics to electric vehicles, which in turn can influence companies’ margins and growth prospects.
synchronous rectificationtechnical
A technique used in electronic power converters where active switches replace conventional one-way diodes to conduct current more efficiently during certain parts of the switching cycle. Think of swapping a rough, one-way flap for a low-friction door: it reduces wasted energy and heat, allowing smaller, cooler and often cheaper power supplies. For investors, it affects product performance, manufacturing costs and energy efficiency—factors that can influence a maker’s margins, market competitiveness and demand for power-sensitive devices.
anti-parallel diodetechnical
An anti-parallel diode is a pair of semiconductor diodes connected in opposite directions across a circuit component so current can flow safely in either direction when needed. Think of it as two one-way valves facing opposite ways that protect sensitive parts from voltage spikes, reduce electrical noise and prevent damage during rapid switching. Investors care because this simple design choice improves product reliability, safety, regulatory compliance and can lower warranty costs and liability risks.
jedectechnical
JEDEC is an industry standards organization that sets common rules and technical specifications for semiconductor components like memory chips, ensuring products from different makers fit and work together. For investors, JEDEC standards matter because they reduce risk and cost by promoting compatibility and quality across the supply chain—think of it as a building code for electronics that helps products get adopted more quickly and makes manufacturing and buying decisions more predictable.
igbttechnical
An IGBT (insulated gate bipolar transistor) is a compact electronic component that switches and controls large amounts of electricity quickly and efficiently, acting like a high-speed on/off valve for power flows. Investors care because IGBTs are key parts in electric vehicles, industrial drives, renewable energy inverters and power grids; their performance, cost and supply can directly affect product efficiency, manufacturing costs and demand across many technology and industrial companies.
r ds(on)technical
RDS(on) is the electrical resistance between the drain and source terminals of a transistor when it is switched fully on; imagine it as the width of a pipe that determines how freely current flows. It matters to investors because lower RDS(on) means less wasted energy, less heat and higher efficiency in electronic products, which can improve device performance, reduce cooling needs, extend battery life and influence a maker’s competitive position and profit margins.

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--(BUSINESS WIRE)--
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 RDS(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.
