ROHM develops 600V withstand voltage Super Junction MOSFET in SOT-223-3 small package

【Lansheng Technology News】ROHM has developed a 600V withstand voltage Super Junction MOSFET*1 "R6004END4 / R6003KND4 / R6006KND4 / R6002JND4 / R6003JND4" in a small SOT-223-3 package (6.50mm × 7.00mm × 1.66mm). The new product is ideal for small lighting applications Applications such as power supplies, electric pumps and motors.

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

Compared with previous TO-252 packaged products (6.60mm × 10.00mm × 2.30mm), the area of the new product is reduced by approximately 31% and the thickness is reduced by approximately 27%, helping to achieve smaller and thinner application products. In addition, the new product also supports wiring patterns (land patterns) on TO-252 package circuit boards, so existing circuit boards can also be used directly.

The five new products are suitable for small power supply and motor applications, each with different characteristics. There are 3 models suitable for small power supplies. "R6004END4" has the characteristics of low noise and is suitable for applications that require noise reduction measures; "R6003KND4" and "R6006KND4" have the characteristics of high-speed switching and is suitable for applications that require low loss and high efficiency. Working application; "R6002JND4" and "R6003JND4" use ROHM's own technology to speed up the reverse recovery time (trr*2) and greatly reduce switching losses. They are "PrestoMOS" products and are very suitable for motor applications.

In addition, in order to speed up the application of these products, ROHM's official website also provides free application guides and various technical materials required for circuit design, as well as SPICE models for simulation and other resources.

The new product will be temporarily put into mass production in November 2023 with a monthly production capacity of 100,000 units (sample price is 400 yen/unit, excluding tax). In addition, new products have also begun e-commerce sales and can be purchased from e-commerce platforms such as Ameya360, Sekorm, Oneyac, and Right IC.

In the future, ROHM will continue to develop different packages and low on-resistance products, continue to expand the Super Junction MOSFET product lineup, and contribute to solving social issues such as environmental protection by helping various devices reduce power consumption.
