Magnachip Commences Full-Scale Mass Production of New 30V MXT LV MOSFET for Electric Power Steering Systems

Dec 18, 2023
  • Developed with highly rugged trench MOSFET technology, the new 30V MXT LV MOSFET ensures a stable power supply for electric power steering

SEOUL, South Korea, Dec. 18, 2023 /PRNewswire/ -- Magnachip Semiconductor Corporation ("Magnachip" or "Company") (NYSE: MX) announced today that the Company has begun full-scale mass production of its new 30V MXT LV Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs)* used in Electronic Control Units (ECUs) of Electric Power Steering (EPS) systems. This MOSFET product is being used by a global automaker.

The new 30V MXT LV MOSFET provides a stable power supply to EPS, assisting a vehicle's directional control through an electric motor. This product also adheres to rigorous AEC-Q101 standards and guarantees a wide operating junction temperature range between -55°C to 175°C.

The new product incorporates a highly rugged trench MOSFET structure in a thick gate oxide, which offers low resistance and excellent switching characteristics. These features reduce switching noise in applications and enhance system performance with high power efficiency. Additionally, the reduced product size, enabled by applying a PDFN 33 package of 3.3mm x 3.3mm, facilitates flexible design options for ECUs.

"Magnachip's new compact and highly reliable MOSFET for EPSs showcases our differentiated technological capabilities," said YJ Kim, CEO of Magnachip. "We will actively expand in the automotive sector with our innovative power solutions and stringent quality control procedures."
