Magnachip launches 8th-gen 40V and 60V MOSFETs
Magnachip Semiconductor has launched is 8th-generation 40V and 60V Medium-Voltage (MV) MOSFETs, designed for use in the Synchronous Rectification (SR) stage of server and PC power systems.
Incorporating the latest Shielded Gate Trench (SGT) technology, the 40V products deliver up to 40 percent improvement in current density and approximately 25 percent faster switching speed compared to the previous generation, according to the company.
The 60V products achieve up to 50 percent improvement in current density and 60 percent faster switching speed. In addition, fast anti-parallel diode technology is applied to rapidly dissipate residual current generated during switching, which can enhance overall system stability.
The devices support a wide operating temperature range of up to 175°C, which enables stable performance even in high-temperature environments, and adopt a compact PDFN56 package to facilitate high-density and compact power designs. Built to meet JEDEC standards, these MOSFETs are designed for use not only in server and high-performance PC power supply units, but also in solar inverters and industrial power systems where high efficiency and reliability are important.
Following the launch of the 0.7mΩ 40V product in May 2025, Magnachip will introducing three additional products: 0.8mΩ 40V, 1.0mΩ 40V, and 1.05mΩ 60V devices.
"These new products are expected to serve as a solution that can enhance both efficiency and reliability in server and high-performance PC power systems," said Hyuk Woo, CTO of Magnachip.
