Magnachip releases new MOSFET with improved thermal management

SEOUL - Magnachip Semiconductor Corporation (NYSE:MX), a $149.3 million market cap semiconductor manufacturer with $233 million in trailing twelve-month revenue, announced Monday the release of a new 80V MXT MV MOSFET featuring a TO-Leaded Top-Side Cooling (TOLT) package, which the company has begun supplying to a leading global electric motor manufacturer.

The new MOSFET, designated MDLT080N017RH, offers improved thermal management through its innovative package design. Unlike conventional TO-Leadless (TOLL) packages that dissipate heat through the bottom, the TOLT package releases heat directly from the top via a mounted metal heat sink.

According to company tests, the new package achieved an average 22% reduction in junction temperature compared to standard TOLL packages. This improvement aims to extend application lifespan and enhance system reliability in thermally demanding applications such as e-scooters and light electric vehicles (LEVs).

"This new 80V MXT MV MOSFET, equipped with the TOLT package, is a testament to Magnachip’s advanced capabilities in high-performance and energy-efficient power semiconductors," said YJ Kim, CEO of Magnachip, in the press release.

The MOSFET features a rated voltage of 80V and RDS(on) of 1.7 mΩ. Beyond e-scooters and LEVs, the company states the component is suitable for e-bikes, personal mobility devices, high-efficiency DC motor drives, battery management systems, and power distribution systems.

Magnachip, with approximately 45 years of operating history, designs and manufactures analog and mixed-signal power semiconductor solutions for various applications including industrial, automotive, communication, consumer, and computing sectors. According to InvestingPro data, the company maintains a strong balance sheet with more cash than debt and a healthy current ratio of 4.51, though it faces near-term profitability challenges. Investors should note that Magnachip will report its next earnings on July 31, with analysts having recently revised their earnings expectations upward.For detailed analysis and 13 additional exclusive insights about Magnachip, including Fair Value estimates and financial health scores, explore the comprehensive Pro Research Report available on InvestingPro.

In other recent news, Magnachip Semiconductor Corporation has announced significant developments related to its financial and operational strategies. The company is enhancing board oversight as it transitions to a dedicated Power business, aiming for $300 million in annual revenue and a 30% gross margin within three years. This strategic initiative, known as the "3-3-3 strategy," is designed to realign product development and improve profitability. Additionally, Chairman Camillo Martino will spend more time at the company’s Korea headquarters to facilitate direct communication and provide regular updates to the Board. In another move, Magnachip’s top executives have agreed to salary reductions as part of a broader effort to align compensation with company performance. CEO Young-Joon Kim will see a 20% reduction in his annual base salary, while CFO Shin Young Park will take a 10% cut.
