Rohm Semiconductor has added a new five-model lineup of compact 600-V Super Junction (SJ) MOSFETs, targeting small lighting power supplies, pumps and motors. The new offering of SJ MOSFETs include the R6004END4, R6003KND4, R6006KND4, R6002JND4 and R6003JND4.
Rohm explained that it has been difficult to reduce the size of the SJ MOSFETS, while maintaining an optimized balance between high breakdown voltage and low on-resistance. In response, the company developed the new models in the SOT-223-3 package (6.50 × 7.00 × 1.66 mm), which offers a smaller and lower profile form factor without sacrificing the performance of conventional products.

Compared to the conventional TO-252 package (6.60 × 10.00 × 2.30 mm), the new power MOSFETs reduce area and thickness by 31% and 27%. Rohm also noted that the same land pattern (footprint) as the TO-252 package can be used, enabling mounting on existing circuit boards without modification.
Three of the models are optimized for compact power supplies. The R6004END4 offers low noise while the R6003KND4 and R6006KND4, capable of high-speed switching, are suited for low loss and high efficiency applications. These devices target applications such as lighting, air conditioners and refrigerators.
The R6002JND4 and R6003JND4 devices use Rohm’s proprietary PrestoMOS power MOSFET technology to achieve significantly lower switching losses by speeding up reverse recovery time (trr) of the built-in diode, making them well-suited for motor-equipped devices such as pumps, fans and copiers.
The SJ MOSFETS are available through Rohm’s online distributors, including Digi-Key, Mouser and Farnell. Rohm expects to expand the family with different packages and lower on-resistance ratings.
