Magnachip Targets Solar and Energy Storage Systems Markets with New Generation of High-Efficiency IGBT Series

Key Terms

insulated gate bipolar transistors technical

An insulated gate bipolar transistor (IGBT) is a semiconductor switch used to control large amounts of electricity in devices like electric motors, power grids, and industrial equipment; think of it as a heavy-duty, electronically controlled light switch on a chip. It matters to investors because its efficiency, cost, size and reliability directly affect product performance, energy use and manufacturing costs in sectors such as electric vehicles and renewable energy, so demand and technology shifts can influence company revenues and margins.

igbt technical

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.

reverse bias safe operating area technical

Reverse bias safe operating area describes the range of reverse voltage and current that a semiconductor device (like a diode or transistor) can tolerate without damage when it is driven in the opposite direction to its normal conducting state. For investors, it signals how robust a product is under stress—stronger reverse-bias tolerance means fewer field failures, lower warranty costs and broader market suitability, similar to a bridge rated to withstand higher loads without collapsing.

to-247 technical

A TO-247 is a standardized plastic-and-metal housing used for high-power semiconductor parts such as power transistors and diodes; it helps spread heat and gives a solid way to bolt the part to a circuit board or heatsink. Investors care because the package affects product durability, cooling needs, manufacturing cost and suitability for power-hungry applications—much like a car’s engine mount affects performance and serviceability—so it can influence market fit and profit margins.

advanced field stop trench technology technical

A manufacturing technique used in semiconductor sensors and light-detecting chips that creates a narrow, controlled trench around the active area to block stray electrical paths and reduce unwanted signal noise. For investors, it matters because devices built with this approach can be smaller, more energy-efficient and more reliable—qualities that can lower production costs, improve product performance and strengthen a company’s competitive position in markets for cameras, optical sensors and related electronics.

kelvin pin technical

A kelvin pin is a precision electrical contact used to separate the path that carries current from the path that measures the tiny voltage across a component, so the measurement isn't skewed by the resistance of the test leads. For investors, its use implies careful, high-precision testing in electronics or battery manufacturing—like using a separate thermometer while heating something—to improve product reliability, manufacturing yield and reduce warranty or recall risk.

- Applies Advanced Field Stop Trench Technology

- Reduces Cell Pitch by 40% Compared to Previous Generation

- Increases Product Scalability Through Improved Current Density and Enhanced RBSOA

- Accelerates Market Expansion with Diverse Capacity Lineup

SEOUL, South Korea--(BUSINESS WIRE)-- Magnachip Semiconductor Corporation (NYSE: MX, “Magnachip”) today announced the launch of its new series of Insulated Gate Bipolar Transistors (IGBTs) designed for solar inverters and industrial Energy Storage Systems (ESS), further strengthening its position in the high-efficiency power semiconductor market.

Magnachip targets solar and energy storage systems markets with new generation of high-efficiency Insulated Gate Bipolar Transistors (IGBTs).

The newly introduced 650V and 1200V new Generation Discrete IGBT products are designed for use in solar inverters and ESS applications. By significantly reducing the cell pitch from the previous generation, Magnachip has achieved a substantial increase in current capacity. In addition, the improved Reverse Bias Safe Operating Area (RBSOA) helps to ensure stable and reliable performance under harsh high-voltage and high-current conditions. The products are available in both standard TO-247 and high-capacity TO-247 Plus packages, providing customers with design flexibility for a wide range of applications.

According to market research firm Omdia, the global solar inverter and ESS market is expected to grow from approximately $1.4 billion in 2024 to $2.7 billion in 2029, representing a compound annual growth rate (CAGR) of approximately 10.6%. With global carbon-neutrality initiatives accelerating, energy efficiency and high power density have become key performance metrics in inverter design.

Magnachip already supplies IGBT products to major domestic and international solar inverter manufacturers, earning recognition for high product quality and advanced technology. With this new product launch, the company is expanding its portfolio to cover a wide capacity range — ­­­from residential inverters to industrial systems up to 150 kW — allowing customers to select suitable products for their operating environment.

The new generation IGBTs leverage Advanced Field Stop Trench technology, with enhanced design and refined process technology compared to the previous generation. Specifically, the cell pitch has been reduced by approximately 40%, significantly increasing current capacity within the same die area. Furthermore, RBSOA, which defines the semiconductor's safe operating limits, has been enhanced by over 30%, ensuring robust stability under high-voltage and high-current conditions. This makes it suitable for a wider range of power applications.

Magnachip plans to further expand its product lineup in the first half of 2026 by introducing a high-current series rated up to 650V 150A, as well as new 750V products. The company also plans to add the ‘TO-247-4Lead’ package, featuring a Kelvin pin for improved switching efficiency, further enhancing its IGBT lineup. This will enable Magnachip to offer a broader range of design options for customers in the solar and ESS markets, which are trending toward higher capacity and efficiency.

"This new generation IGBT series enhances efficiency and reliability through refined process technologies," said Hyuk Woo, CTO of Magnachip. "Building on our market-proven technology and production capabilities, we will continue to expand our solution lineup to better address diverse customer needs."
