Magnachip Launches Mass Production of 40V MOSFETs for Electric Vehicle Pumps

What’s Happening: Magnachip Semiconductor Corporation (NYSE: MX) has commenced full-scale mass production of its new 40V MXT Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) specifically designed for Electric Water Pumps (EWPs) and Electric Oil Pumps (EOPs) in electric vehicles (EVs).

Why It Matters: The newly developed 40V MXT MOSFET (AMDUA040N070RH) comes in a Power Dual Flat No-lead (PDFN) 56 dual package, which reduces the printed circuit board size by 50% compared to using two 40V single-packaged MOSFETs. The compact size offers increased flexibility in system design, making AMDUA040N070RH well-suited for EWPs, EOPs, and power seat modules in EVs. The growing demand for eco-friendly applications makes this development significant for the EV market.

Key Points:

  • The low RDS(on) enabled by the PDFN56 package decreases conduction losses, allowing for more efficient application control.
  • AMDUA040N070RH is fully AEC-Q101 qualified, ensuring performance and stability due to the enhanced design of its core cells and terminations for automotive applications.
  • Market research firm Omdia projects the Si MOSFET market for hybrid and EVs will grow 11% annually from 2023 to 2026.

Bottom Line: Magnachip’s latest innovation, the 40V MXT MOSFET, is poised to contribute to the growing market for eco-friendly automotive applications with its compact size and energy-efficient design. Magnachip CEO YJ Kim emphasized the company’s commitment to delivering innovative solutions for the evolving EV market, stating, “As a provider of high-performance MOSFETs, Magnachip will continue to deliver innovative solutions to serve the growing demand for eco-friendly applications.”
