– The PDFN56 dual package enables small footprint and low conduction losses

SEOUL, South Korea, March 21, 2023 – Magnachip Semiconductor Corporation (“Magnachip”) (NYSE: MX) announced today that the company began full-scale mass production of its new 40V MXT Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET)1 optimized for the Electric Water Pumps (EWPs) and Electric Oil Pumps (EOPs) in electric vehicles (EVs).

This 40V MXT MOSFET (AMDUA040N070RH) comes in a Power Dual Flat No-lead (PDFN) 56 dual package to reduce the printed circuit board size by 50%, as compared to using two 40V single-packaged MOSFETs. The compact size provides great flexibility in system design and, as a result, AMDUA040N070RH is well-suited to EWPs, EOPs and even the power seat modules of EVs.

The low R_DS(on)2 enabled by the PDFN56 package reduces conduction losses, which means applications can be controlled efficiently. In addition, AMDUA040N070RH is fully AEC – Q101 qualified for its performance and stability, because of the enhanced design of its core cells and terminations for automotive applications.

Omdia, a global market research firm, estimates that the Si MOSFET market for hybrid and EVs will grow 11% annually from 2023 to 2026.

“Since 2008 we have strengthened our technological capabilities in the power solutions area” said YJ Kim, CEO of Magnachip. “As a provider of high-performance MOSFETs, Magnachip will continue to deliver innovative solutions to serve the growing demand for eco-friendly applications.”
