The switching speeds of the newly developed Gen6 SJ MOSFETs have been improved by approximately 23%, reducing the R_SP of applications by about 40% compared to the previous generation, thereby enhancing the Figure of Merit by 40%.

Additionally, a Zener diode is embedded between the gate and source to enhance reliability and protect the SJ MOSFETs from ESD-induced damage. The chip sizes of the new products are also approximately 30% smaller than their predecessor product.

The new product lineup consists of 600V, 650V, and 700V voltage ratings and is available in 7 package types, including TO220, TO220FT, SOT223, PDFN88, and D²PAK, with high-demand options, such as DPAK and TO220F.

As a result, these SJ MOSFETs are well-suited for various applications requiring high power efficiency, including AI TVs, smart refrigerators, AI laptop adapters and power supplies. According to market research firm Omdia, the global smart home device market is projected to grow by 20% annually from 2025 to 2028.

"With the successful launch of 25 new Gen6 SJ MOSFETs integrating Magnachip’s latest technology, we have further strengthened our product lineup to meet our customers' evolving technical requirements," said YJ Kim, CEO of Magnachip. "By delivering optimal power solutions for the AI, industrial applications and smart home appliances, we aim to contribute to the growth and success of our customers in these sectors, and further advance our technology and market leadership as we transition to a pure-play Power company.”
