New 800 V CoolMOS P7 series from Infineon Demonstrates Ground-breaking Efficiency and Thermal Performance

new 800 V CoolMOS P7 series

Infineon Technologies unveils the new 800 V CoolMOS P7 series based on the superjunction technology demonstrating best-in-class performance with exceptional ease-of-use.

This new product family from Infineon is touted to be a perfect fit for low power SMPS applications with addressing the market needs in performance, ease of design, and price/performance ratio.

It is sought to mainly focus on flyback topologies which are typically found in applications like adapter, LED lighting, audio, industrial and auxiliary power.

The new 800 V CoolMOS P7 series offers

  • Up to 0.6 percent efficiency gain.
  • Translates into 2 to 8 °C lower MOSFET temperature compared to the CoolMOS C3 or to competitor parts tested in typical flyback applications.
  • This new benchmark results from a combination of optimized device parameters: including the reduction of more than 50 percent in Eoss and Qg, as well as a reduced Ciss and Coss.
  • The further improved performance enables higher power density designs through lower switching losses and better DPAK RDS(on)
  • Overall, this helps customers to save BOM costs and reduce assembly efforts.
  • Ease-of-use of is an intrinsic feature designed into this product family.

Additionally, the integrated Zener Diode significantly improves ESD ruggedness, thus reducing ESD related production yield losses. The MOSFET is easy to drive and to design-in due to its industry leading V(GS)th of 3 V and the smallest VGS(th) variation of only ±0.5 V.

This combination allows for lower driving voltage and lower switching losses. Additionally, it helps to avoid unintentional operation in the linear region.


The family of 800 V CoolMOS P7 MOSFETs will be available in twelve RDS(on) classes and in six packages to fully address the needs of target applications. Products with RDS(on) of 280 mΩ, 450 mΩ, 1400 mΩ and 4500 mΩ can be ordered now.
