Magnachip Launches 8th-Generation 40V and 60V MV MOSFETs for Server and High-Performance PC Power Supplies

Magnachip Semiconductor launched of its new 8th-generation 40V and 60V Medium-Voltage (MV) MOSFETs, designed for server and high-performance PC power supply units. The devices target the Synchronous Rectification (SR) stage of server and PC power systems. They incorporate Advanced Shielded-Gate Trench (SGT) technology. Compared to the previous generation, the 40V products provide up to 40% improvement in current density and approximately 25% faster switching speed. The 60V products provide up to 50% improvement in current density and 60% faster switching speed. Fast anti-parallel diode technology is applied to rapidly dissipate residual current generated during switching.

 

The MOSFETs support a wide operating temperature range of up to 175°C and use a compact PDFN56 package. They meet JEDEC standards and are designed for server and high-performance PC power supply units, as well as solar inverters and industrial power systems.

 

Following the May 2025 launch of the 0.7mΩ 40V product, Magnachip introduced three additional devices: 0.8mΩ 40V, 1.0mΩ 40V, and 1.05mΩ 60V. The full Server/PSU MXT MV MOSFET Series includes:

 

- MDU040N007PSLVRH: 40V, 0.7mΩ max RDS(on) at VGS=10V, 1.8V typ. Vth, PDFN56 package

- MDU040N008PSVRH: 40V, 0.8mΩ max RDS(on...
