ROHM has developed dual MOSFETs that integrate two 100V chips in a single package – ideal for fan motor drive applied in communication base stations and industrial equipment. New five-models have been added as part of the HP8KEx/HT8KEx (Nch+Nch) and HP8MEx (Nch+Pch) series.
Recent years have seen a transition to higher voltages from conventional 12V/24V to 48V systems in communication base stations and industrial equipment, – intending to achieve higher efficiency by reducing current values. In these situations, switching MOSFETs are required a withstand voltage of 100V to account for voltage fluctuations, as 48V power supplies are also used in the fan motors for cooling these applications.
However, increasing the breakdown voltage raises ON resistance (RDS(on)) (which is in a trade-off relationship), leading to decreased efficiency, making it difficult to achieve both lower RDS(on) and higher breakdown voltage. Moreover, unlike multiple individual drive MOSFETs normally applied in fan motors - dual MOSFETs that integrate two chips in one package are increasingly being adopted to save space.
In response, ROHM developed two new series – the HP8KEx/HT8KEx (Nch+Nch) and the HP8MEx (Nch+Pch) – that combine Nch and Pch MOSFET chips using the latest processes. Both series achieve the industry’s lowest RDS(on) by adopting new backside heat dissipation packages with excellent heat dissipation characteristics. As a result, RDS(on) is reduced by up to 56% compared with standard dual MOSFETs (19.6mΩ for the HSOP8 and 57.0mΩ for the HSMT8 Nch+Nch), contributing to significantly lower set power consumption.
At the same time, combining two chips in a single package provides greater space savings by reducing area considerably. For example, replacing two single-chip TO-252 MOSFETs with one HSOP8 decreases footprint by 77%.
Next, ROHM will continue to expand its dual MOSFET lineup to withstand voltages ideal for industrial equipment while also developing low-noise variants. This is expected to contribute to solving social issues such as environmental protection by saving space and reducing power consumption in various applications.
Application Examples
– Fan motors for communication base stations
– Fan motors for factory automation, and other industrial equipment
– Fan motors for data center servers, etc.Original – ROHM

Siltronic AG officially inaugurated the extension to its crystal pulling hall at the Freiberg site. The new production area provides space for the latest generation of crystal pulling systems, which are used to produce silicon monocrystals for wafer production under cleanroom conditions. In total, several hundred million euros were invested in the construction and around 60 jobs were created.
“This investment is a clear commitment to our Saxon location. In addition, the modernization helps us to maintain our position as one of the world’s technology leaders and it strengthens our position as the only major Western wafer manufacturer”, said Dr. Michael Heckmeier, CEO of Siltronic AG, at the opening. The Freiberg site in Saxony is one of four production sites of the group, which manufactures in Germany, Singapore and the USA.
With a usable area of 20,000 square meters, the extension building is almost as large as three soccer fields. Here, man-sized silicon monocrystals are produced in a process that takes five to seven days. The so-called ingots have a diameter of around 300 millimeters and weigh several hundred kilograms. In a complex process under cleanroom conditions, they are processed into wafers – extremely thin slices of silicon. Siltronic’s customers use the wafers to manufacture microchips, which can be found in everyday items such as tablets, smartphones and electric cars, as well as wind turbines and aircrafts. The semiconductor industry is receiving tailwind from the megatrends of artificial intelligence, digitization and electromobility.
Siltronic has invested more than one billion euros at the site since acquiring Freiberger Elektronikwerkstoffe GmbH in 1995. “With our investments, we believe we are well prepared for the future, to be at the forefront in a challenging market environment,” Heckmeier explained. Currently around 1,000 people are employed at the site in Freiberg, Saxony.
