Magnachip introduces 600V SJ MOSFETs with fast recovery body diodes

Magnachip has introduced 600V super junction MOSFETs with RDS(on) as low as 44 mOhm for EV chargers and servers. There are nine products in the 600V MOSFET family, featuring the proprietary design technology.

Magnachip’s design provides specific on-resistance (RSP) reduction of about 10 per cent, achieved while maintaining the same cell-pitches of previous generation MOSFETs.

The 600V super junction MOSFETs are equipped with a fast recovery body diode. The proprietary technology significantly enhances system efficiency with reduced reverse recovery time (trr) and switching loss. Therefore, the figure of merit to evaluate general performance of MOSFETs was improved by more than 10 per cent compared to the previous generation, said Magnachip. The 600V super junction MOSFETs can be used widely in industrial applications, such as solar inverters, energy storage systems, uninterruptible power supply systems, and a variety of electronics.

One of the nine MOSFETs is the MMQ60R044RFTH which offers a low RDS(on) of 44 mOhm, making it suitable for electric vehicle chargers and servers. 

“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. 

Magnachip Semiconductor is a designer and manufacturer of analogue and mixed-signal semiconductor platforms for communications, IoT, consumer, computing, industrial and automotive applications. The company has more than 40 years’ of operating history, owns a portfolio of approximately 1,100 registered patents and pending applications, and has extensive engineering, design and manufacturing process expertise.
