The switching speeds of the newly developed Gen6 SJ MOSFETs (Super Junction Metal-Oxide-Semiconductor Field-Effect Transistors) have been improved by approximately 23 %, reducing the RSP 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.
