ROHM has added a lineup of compact 600V Super Junction MOSFETs R6004END4 / R6003KND4 / R6006KND4 / R6002JND4 / R6003JND4. These devices are ideal for small lighting power supplies, pumps, and motors.
In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated – spurring the demand for compact MOSFETs that are essential for switching operation.
Generally, however, it has been difficult to reduce the size of Super Junction MOSFETs while maintaining an optimal balance between high breakdown voltage and low ON resistance. In response, after reviewing the shape of the mounted chip, ROHM was able to develop 5 models in the SOT-223-3 package (6.50mm × 7.00mm × 1.66mm) – providing a smaller, lower profile form factor without compromising the performance of conventional products.
Compared to the conventional TO-252 package (6.60mm × 10.00mm × 2.30mm), ROHM’s new products reduce area and thickness by 31% and 27% – contributing to smaller, lower profile applications. At the same time, the same land pattern (footprint) as the TO-252 package can be used, enabling mounting on existing circuit boards without modification.
Offering distinctive features, three of the models optimized for compact power supplies. The R6004END4, characterized by low noise, is suitable for applications where noise is a concern, while the R6003KND4 and R6006KND4, capable of high-speed switching, are ideal for sets requiring low loss, high efficiency operation.
The R6002JND4 and R6003JND4 utilize proprietary PrestoMOS technology to achieve significantly lower switching losses by speeding up reverse recovery time (trr), making them well-suited for motors-equipped devices.
Supporting materials such as application notes, technical documents, and SPICE simulation models for each product are available on ROHM’s website free of charge to enable quick market introduction.
Going forward, ROHM will continue to expand its Super Junction MOSFET lineup in different packages and even lower ON resistances that contribute to solving social issues such as environmental protection by reducing power consumption in variety devices.

Magnachip Semiconductor Corporation announced that the Company has begun mass production of two new 650V Super Junction Metal-Oxide-Semiconductor Field-Effect Transistors (SJ MOSFETs) offerings.
These two 650V SJ MOSFETs (MMUB65R090RURH, MMUB65R115RURH) utilize an innovative PDFN88 package, which significantly reduces their thickness and size. The thickness has been reduced by approximately 81% compared to D2PAK products and 63% compared to DPAK products, while the overall footprint has been reduced to about 41% of D2PAK SJ MOSFETs.
These new SJ MOSFETs — upgraded by the PDFN88 package — offer excellent design flexibility, efficient heat dissipation, and low RDS(on) (the resistance value between the drain and the source of MOSFETs during on-state operation) characteristics. As a result, they are well-suited for various applications that require compact size and high efficiency, such as OLED TVs, servers, lighting products, laptop chargers and adapters.
“Magnachip will continue to develop high-performance power solutions enhanced by new packaging technology, building upon the successful mass production of these 650V SJ MOSFET products,” said YJ Kim, CEO of Magnachip. “We aim to drive expansion in the electronics market through our extended product portfolio and rigorous quality control.”
