Infineon – 800V CoolMOSTM P7 Series: A New Benchmark in Efficiency and Thermal Performance


Infineon Logo     NPI_LOGO
The latest 800V CoolMOSTM P7 series sets a new benchmark in 800V superjunction technol- ogies and combines best-in-class performance with state-of-the-art ease-of-use, resulting from Infineon’s more than 18 years of pioneering superjunction technology innova- tion. This product family offers 0.1% to 0.6% efficiency gain and 2°C to 8°C lower MOSFET temperature as compared to 800V CoolMOSTM C3 tested in flyback based applications. Such best-in-class performance comes from a combination of various optimized device parameters such as reduced Eoss, Qg, Ciss and Coss.


Ease-of-use is an intrinsic feature designed into this product family. The integrated Zener Diode ESD protection significantly improves ESD robust- ness, thus reducing ESD-related yield loss. With best-in-class V(GS)th of 3V, CoolMOSTM P7 is easy to drive and the smallest V(GS)th variation of only ±0.5V makes it easy to design-in. This product family continues to deliver well recognized best- in-class CoolMOS quality.

In addition, CoolMOSTM P7 offers a new best-in- class RDS(on) of 280mΩ available in DPAK, more than 50% lower than the nearest 800V MOSFET competitor. This new benchmark enables higher power density designs, BOM savings, as well as lower assembly cost.

Evaluation Board #EVAL_45W_19V_FLYB_P7

This 45W adapter evaluation board is intended to be a functional, form-fitting test platform for low-cost charger and adapter applications to show the operation of the IPA80R450P7 800V CoolMOSTM P7 as well as the overall controller design. The evaluation board is designed around the Infineon ICE2QS03G Quasi-Resonant (QR) Flyback controller for improved switching losses which allows higher power density designs and lower radiated and conducted emissions.
