Infineon Technologies
introduced the CoolSiC Schottky diode 650-V G6, built upon the distinctive
characteristics of the G5, providing reliability, quality, and increased efficiency.
The CoolSiC G6 diodes are a perfect complement to the 600-V and 650-V CoolMOS 7
families and are aiming at current and future applications in server and PC
power, telecom equipment power, and PV inverter applications.


The CoolSiC Schottky diode 650-V G6 has a new layout, cell structure, and
proprietary Schottky metal system, resulting in an industry benchmark VF (1.25 V),
and a QC
x VF
figure of merit (FOM) 17% lower than the previous generation. In addition, the
new G6 diode makes use of the SiC strong characteristics of
temperature-independent switching behavior with no reverse recovery charge. The
design of the device provides improved efficiency over all load conditions
along with increased system power density, resulting in reduced cooling requirements,
increased system reliability, and extremely fast switching.
