Magnachip Introduces 8th-Gen 150V MXT MOSFET for Light Electric Vehicles

Magnachip’s eighth-generation 150V MXT MOSFET features lower R_DS(on) and a TOLL package to enable motor controllers and battery management systems to be managed efficiently

Magnachip Semiconductor Corporation announced that the company has launched its eighth-generation 150V MXT Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET)¹ optimized for Light Electric Vehicle (LEV) motor controllers and battery management systems (BMSs).

Energy efficiency plays a critical role in electric devices when it comes to power consumption and product stability. This newly-released MOSFET (MDT15N054PTRH) features Magnachip’s eighth-generation trench MOSFET technology to lower R_DS(on)² by 28%, as compared to the previous generation. Based on the enhanced design of the core cell and termination, a high figure of merit can be achieved and an increase in the total gate charge³ can be avoided.

MDT15N054PTRH is available in a surface mount device TO-Leadless (TOLL) package to reduce product size and improve heat dissipation. The energy efficiency is also significantly enhanced by fast switching, while enabling high power density. In addition, a guaranteed operating junction temperature from -55°C up to 175°C and a high level of avalanche ruggedness help the new MXT MOSFET to exceed the performance requirements of LEV motor controllers and BMSs.

“Beginning in 2008 we have released more than 40 MOSFET products for motor controllers and battery management systems and, since 2017, most of them have been made for LEV applications,” said YJ Kim, CEO of Magnachip. “As a provider of high-performance MOSFETs, Magnachip will continue to deliver innovative solutions that meet the sophisticated requirements of the market.”
