Magnachip’s proprietary design provides specific on-resistance (RSP) reduction of about 10%, and this result was achieved while maintaining the same cell-pitches of previous generation MOSFETs.
In addition, the new product family is equipped with a fast recovery body diode that significantly enhances system efficiency with reduced reverse recovery time (trr) and switching loss. As a result, the figure of merit to evaluate general performance of MOSFETs has been improved by more than 10% compared to the previous generation. As such, these 600V SJ MOSFETs can be used widely in industrial applications, such as solar inverters, energy storage systems, uninterruptible power supply systems, and a variety of electronics.
Among these new MOSFETs, the MMQ60R044RFTH product offers a very low RDS(on) of 44mΩ, making it suitable for electric vehicle chargers and servers.
According to figures from Omdia, a global market research firm, the compound annual growth rates of Si MOSFET markets for hybrid & electric vehicles and servers is estimated to be 11% and 7%, respectively, from 2023 to 2026.
“Now that we have introduced these 600V SJ MOSFET products, we are aiming to unveil new 650V and 700V SJ MOSFET products with fast recovery body diode in the second half of 2023,” said YJ Kim, CEO of Magnachip. “These new MOSFETs represent a notable achievement, and we will build upon this success to deliver next-generation power solutions for rapidly changing market requirements and customer expectations.”
