Infineon Technologies Co., Ltd. recently in the application of power electronics Conference and Exhibition (APEC) launched the third generation of thinQ! SiC Schottky diodes. New thinQ! Diode rated current in any condition are devices with the industrys lowest capacitance, high switching frequency in light load conditions and to enhance the efficiency of the entire system, thus helping to reduce the cost of power conversion system. In addition, Infineon introduced the third generation of SiC Schottky diodes is the industrys most complete types of silicon carbide Schottky diode series, including not only TO-220 package (two-pin version of the real) product, but also for high power density design DPAK surface mount packages.
  
SiC Schottky diode is the main application field switch-mode power supply (SMPS) of the active power factor correction (CCM PFC) and solar inverters and motor drives and other AC / DC and DC / DC power conversion applications.

Compared with the second-generation products, Infineons new SiC Schottky diode to reduce the device capacitance of about 40%, thereby reducing the switching losses. For example, the operating frequency of 250 kHz for Power Factor Correction 1kW-class in the 20% load conditions the overall energy efficiency will be increased by 0.4%. Higher switching frequency allows the use of lower cost, smaller passive components (such as inductors and capacitors) to achieve higher power density design. Lower power consumption also reduces the heat sink and fan size and the number of requests, thus reducing system cost and improve reliability. Infineon expects to certain SMPS applications reduce system cost by 20%.

Infineon diversified industrial and high-voltage MOS e-marketing operations, Andreas Urschitz said: "Infineon took the lead in the global scope of the provision of SiC Schottky diodes, in 2001 the first batch of products. The last 8 years, Infineon in a number of Schottky diodes on silicon carbide technology for a number of significant improvements, such as the surge current stability, switching performance and product cost, so that the benefit of the wider application of SiC technology and lower cost solutions. SiC is a The real innovative technology to help fight global climate change and promote energy-efficient lighting system, solar energy and the development of the market. It fully demonstrates that the power management market, Infineons leading position and commitment to market development in the
