600V SuperJunction MOSFETs for lighting, pumps and motors

Rohm has launched a range of 600V SuperJunction MOSFETs in SOT-223-3 packages with low noise, high-speed switching, and fast reverse recovery time for lighting power supplies, pumps and motors.

In recent years, power supplies for lighting and motors for pumps are required to be smaller, spurring the demand for compact SuperJunction MOSFETs that are essential for switching operation.

Generally, however, it has been difficult to reduce the size of SuperJunction 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), the MOSFETs 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 use Rohm’s 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 plans to expand its SuperJunction MOSFETs 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.
