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.

Alpha and Omega Semiconductor Limited (AOS) announced the AONA66916, a 100V MOSFET packaged in the company’s innovatively designed top and bottom side cooling DFN 5 x 6 package. Designers have long trusted AOS power semiconductors as essential components that help them meet a wide variety of high performance application requirements.
Now, in delivering a state-of-the-art package that keeps its semiconductor products cooler, AOS is taking a huge step in enabling engineers to develop more efficient designs in telecommunications and industrial applications that must frequently operate in harsh conditions.
Typically, when using the standard DFN 5×6 package, the bottom contact is the main contributor for cooling, and most of the heat generated by the Power MOSFETs will be transferred to the PCB. This increases the PCB thermal management design considerations to meet system requirements. AOS’ new top and bottom cooling DFN 5×6 package is designed to achieve the highest heat transfer between the exposed top contact and heat sink due to its large surface contact area construction.
This allows the device to achieve a low thermal resistance (Rthc-top max) of 0.5°C / W with results being transferred to the PCB board, enabling significant thermal performance improvements. The top exposed DFN 5×6 package of the AONA66916 shares the same 5mm x 6mm footprint as AOS’ standard DFN 5×6 package, eliminating the need to modify existing PCB layouts.
Another benefit of the AONA66916 is that it utilizes AOS’ 100V AlphaSGT™ technology, providing excellent FOM for balanced performance in hard switching applications. AONA66916 has a maximum RDS(on) rating of 3.4mOhms and has a 175°C junction temperature rating.
“Cooling the power MOSFET in high power design can be challenging, and AOS has successfully addressed this essential issue with our advanced top exposed package design. It not only enables better thermal transfer from its top side exposed contact to heat sink due to large exposed surface area, our new package delivers a much cooler device that contributes to a more efficient and robust final design,” said Peter H. Wilson, Marketing Sr. Director of the MOSFET product line at AOS.

Mitsubishi Electric Corporation announced the coming release of six new J3-Series power semiconductor modules for various electric vehicles (xEVs), featuring either a silicon carbide metal-oxide semiconductor field-effect transistor (SiC-MOSFET) or a RC-IGBT (Si), with compact designs and scalability for use in the inverters of electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). All six J3-Series products will be available for sample shipments from March 25.
The new power modules will be exhibited at the 38th Electronics R&D, Manufacturing and Packaging Technology Expo (NEPCON JAPAN 2024) from January 24 to 26 at Tokyo Big Sight, Japan, as well as other exhibitions in North America, Europe, China and additional locations.
As power semiconductors capable of efficiently converting electricity expand and diversify in response to decarbonization initiatives, the demand is increasing for SiC power semiconductors offering significantly reduced power loss. In the xEV sector, power semiconductor modules are used widely in power conversion devices such as inverters for xEV drive motors.
In addition to extending the cruising range of xEVs, compact, high-power, high-efficiency modules are needed to further downsize batteries and inverters. But due to the high safety standards set for xEVs, power semiconductors used in drive motors must be more reliable than those used in general industrial applications.
Development of these SiC products was partially supported by Japan’s New Energy and Industrial Technology Development Organization (NEDO).
