Delivering reliable and cost-effective top performance

Megatrends like digitalization, urbanization, and electro mobility lead to increased power consumption, pushing energy efficiency into focus. Infineon responds by offering full system solutions from one source - building no longer only on its renowned silicon technology, but also on innovative wide-bandgap devices such as SiC-based CoolSiC™ MOSFETs.

Infineon’s CoolSiC™ MOSFET technology leverages the strong physical characteristics of silicon carbide (SiC) such as the capability to operate at higher voltages, temperature and frequencies. By adding unique features Infineon manages to further increase the device performance. Applying Infineon’s superior TRENCH technology, the use of CoolSiC™ MOSFETs guarantees lowest losses in the application and the highest reliability in operation.

CoolSiC™ MOSFETs are suitable for high temperature and harsh operations. Resultingly, a simplified and cost-effective deployment of highest system efficiency in a broad range of applications is possible.
