950V CoolMOS™ P7
Perfect fit for PFC and flyback topologies
Designed to meet the growing consumer needs in the high voltage MOSFETs arena, the latest 950 V 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 50 V more blocking voltage than its predecessor 900 V CoolMOS™ C3, the new 950 V CoolMOS™ P7 series delivers outstanding performance in terms of efficiency, thermal behavior and ease-of-use.
Same as in the remaining P7 family members, a Zener diode ESD protection is included in the 950 V CoolMOS™ P7 series, enhancing ESD robustness significantly. In return, ESD-related yield loss is reduced which guarantees remarkable ease-of-use. CoolMOS™ P7 is developed with best-in-class VGS(th) of 3 V and a narrow tolerance of only ±0.5 V, which makes it easy to drive and design-in.
Compared to competition, the 950 V CoolMOS™ P7 delivers best-in-class efficiency and thermal performance. Plug-and-play at 90 VAC in a 40 W 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.
With over 20 years of experience in superjunction technology, Infineon introduces 950 V 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.
