Infineon Technologies has launched its CoolMOS CS Server series of high-performance power transistors, designed specifically for power supplies used in computer servers and other high-power-density applications such as telecom equipment and flat panel displays. Heat generated by the power supply can be a major problem, however, Infineon says the new family of power transistors will enable power supply designs that are smaller, more energy efficient and generate significantly less heat than alternative power transistors.
The new CoolMOS CS Server MOSFETs have the world's lowest on-state resistance of 99 mΩ in a standard TO 220 package, or 45 mΩ in a standard TO 247 package, coupled with the industry's fastest switching speeds of 150 V/ns and a 600 V voltage blocking capability, according to the company.
At the 2005 Applied Power Electronics Conference, Infineon demonstrated a 1000 W reference design for a server power supply, with one 99 mΩ CoolMOS CS power transistor. It produces 1,5% higher efficiency compared to a similar power supply made using two commonly available, standard 250 mΩ MOSFETs, placed in parallel. This increased efficiency results in more than 10% system cost reduction per watt. It also enables the designer to realise a smaller form factor for the system.
Infineon also demonstrated a 1500 W power factor correction design, which achieves 99% efficiency with a 99 mΩ CoolMOS CS power transistor - an industry record it claims.
