Unique Success Story of CoolMOS™ Technology: Infineon launches 650V MOSFET with Integrated Fast Body Diode and crosses the 3.5 Billionth High-Voltage MOSFET to Advance Energy Efficiency Worldwide

Neubiberg, Germany – February 3, 2011 – On January 19, 2011, the 3.5 billionth CoolMOS™ high-voltage MOSFET came off the production line at the company’s manufacturing facility in Villach, Austria, making Infineon the world’s most successful supplier of these 500 to 900V transistors. Continuous improvement of the chip architecture to ensure constant technological optimization of the CoolMOS™ transistors has paved the way for this success.

55 years after the transistor was invented, Infineon was awarded the Innovation Award of the German Industry in 2002 for its revolutionary CoolMOS™ transistor technology. The high-voltage power transistors raise energy efficiency in an array of applications, such as PC power supplies, servers, solar power inverters, lighting and telecommunications power supplies. These energy-saving chips are now also key components in consumer electronics devices, for instance in flat-screen TVs and games consoles. Using energy efficiently and saving energy are becoming key requirements for all electrically powered industrial or household applications. Infineon’s energy-efficient semiconductor solutions allow saving as much as 25 percent of global power consumption. Thanks to the CoolMOS™ chips a server board for instance needs about 30 Watt less of power. Projected on to around 60 million servers worldwide, energy savings would add up to 1.8 gigawatts, which is equivalent to the output of a nuclear power station.

“We have continuously developed the CoolMOS™ transistor technology to maximize the efficiency thus offering our customers a clear competitive edge. We make a decisive contribution to the sustainable conservation of resources for future generations”, said Andreas Urschitz, Vice President & General Manager Power Management and Supply Discretes at Infineon Technologies. “ The solar energy harnessing system for the soccer stadium in Kaohsiung, Taiwan, is a fine example of the successful deployment of our CoolMOS™ technology. CoolMOS™ chips in solar inverters ensure the highest possible energy efficiency. Therewith, the solar plant generates 1.1 million kilowatt-hours power and saves about 660 tons CO2 per year.”

Next Technology Step is the new 650V CoolMOS™ CFD2

Infineon is now rolling out another important innovation with its latest generation of high-voltage CoolMOS™ MOSFETs. The new 650V CoolMOS™ CFD2 is the world’s first high-voltage transistor with a drain-source voltage of 650V and an integrated fast body diode. The softer commutation behavior and therefore better EMI characteristics give this product a clear competitive advantage. The CoolMOS™ CFD 2 650V product portfolio provides all benefits of fast switching super-junction MOSFETs like better light load efficiency, reduced gate charge, easy implementation and outstanding reliability. Infineon expects the greatest market potential for this transistor to be in solar power inverters, server computers, LED lighting and telecommunications equipment.
