KUC321AE ROHM develops 600V voltage resistant Super Junction MOSFETs

ROHM (headquartered in Kyoto City, Japan), a world-renowned semiconductor manufacturer, has developed a 600V voltage resistant Super Junction MOSFET*1 "R6004END4 / R6003KND4 / in a SOT-223-3 compact package (6.50mm x 7.00mm x 1.66mm) R6006KND4 / R6002JND4 / R6003JND4 ", the new product is ideal for applications such as lighting small power supplies, electric pumps and motors.

In recent years, as the performance of small power supplies for lighting and electric pump motors has improved, the demand for smaller MOSFETs that play a switching role in these applications has soared. In general, for Super Junction MOSFETs, it is difficult to further reduce the size while maintaining the ideal balance of high voltage resistance and low on-resistance characteristics. This time, ROHM has developed five new, smaller and thinner SOT-223-3 packages by improving the shape of the internal chip without sacrificing the performance of previous products.

Compared TO the previous TO-252 package (6.60mm×10.00mm×2.30mm), the new product has approximately 31% less area and 27% less thickness, enabling smaller, thinner applications. In addition, the new product also supports the wiring pattern (pad pattern) on the TO-252 packaged circuit board, so it can also directly use the existing circuit board.

The five new products are suitable for small power supply and motor applications, each with different characteristics. There are three models for small power supplies, the "R6004END4" features low noise, suitable for applications requiring noise reduction measures; The "R6003KND4" and "R6006KND4" feature high-speed switches for applications requiring low loss and high efficiency. The "R6002JND4" and "R6003JND4" use ROHM's own technology to accelerate reverse recovery time (trr*2) and greatly reduce switching losses, and are "PrestoMOS" products, ideal for motor applications.
