CoolMOS™ C7 superjunction MOSFET offers best-in-class performance in PFC and LLC topologies
The new 600V CoolMOS ™ C7 superjunction (SJ) MOSFET series from Infineon offers a ~50% reduction in turn-off losses (E oss ) compared to the CoolMOS™ CP, offering an outstanding level of performance in PFC, TTF and other hard-switching topologies.
Efficiency and TCO (total cost of ownership) applications such as hyperdata centers and high efficiency telecom rectifiers (>96%) benefit from the higher efficiency offered by CoolMOS ™ C7. Gains of 0.3% to 0.7% in PFC and 0.1% in LLC topologies can be achieved. In the case of a 2.5kW server PSU, for example, using 600V CoolMOS ™ C7 SJ MOSFETs in a TO-247 4pin package can result in energy cost reductions of ~10% for PSU energy loss.
