950V CoolMOS™ P7

Designed to meet the growing consumer needs in the high voltage MOSFETs arena, the latest 950V CoolMOS™ P7 technology focuses on the low power SMPS market. This new P7 family addresses applications ranging from lighting, smart meter, mobile phone charger, notebook adapter, to AUX power supply and industrial SMPS.

Offering 50V more blocking voltage than its predecessor 900V CoolMOS™ C3, the new 950V CoolMOS™ P7 series delivers outstanding performance in terms of efficiency, thermal behavior and ease-of-use.

Key features and benefits of 950V CoolMOS™ P7 SJ MOSFET

Key features

  • Best-in-class FOM RDS(on) Eoss; reduced Qg, Ciss and Coss
  • Best-in-class DPAK RDS(on) of 450mΩ
  • Best-in-class VGS(th) of 3V and smallest VGS(th) variation of ±0.5V
  • Integrated Zener diode ESD protection up to Class 2 (HBM)
  • Best-in-class quality and reliability

Key benefits

  • Up to 1% efficiency gain and 2°C to 10°C lower MOSFET temperature, compared to CoolMOS™ C3
  • Enabling higher power density designs, BOM savings, and lower assembly cost
  • Easy to drive and to design-in
  • Better production yield by reducing ESD related failures
  • Less production issues and reduced field returns

As the all other P7 family members, the 950V CoolMOS™ P7 series comes with an integrated Zener diode ESD protection. The integrated diode considerably improves ESD robustness, thus reducing ESD-related yield loss and reaching exceptional ease-of-use levels. CoolMOS™ P7 is developed with best-in-class VGS(th) of 3V and a narrow tolerance of only ±0.5V, which makes it easy to drive and design-in.

With over 20 years of experience in superjunction technology, Infineon introduces 950V CoolMOS™ P7 with best-in-class DPAK on-resistance (RDS(on)). This SMD device comes with the RDS(on) of 450 mΩ – more than 60% lower RDS(on) compared to the nearest competitor. Such low RDS(on) value enables higher density designs while decreasing BOM and assembly cost.

Compared to competition, the 950V CoolMOS™ P7 delivers best-in-class efficiency and thermal performance. Plug-and-play at 90VAC in a 40W adapter reference design, featuring the snubberless concept, demonstrates excellent efficiency gains of up to 0.2% and lower MOSFET temperature of up to 5.2°C compared to similar competitor technology.
