Mouser – New MOSFETs ideal for low-power switch mode power supply applications

Mouser is the first to stock the new CoolMOS P7 800V MOSFETs from Infineon Technologies. The new product family, the company’s latest offering in superjunction technologies, is ideal for low-power switch mode power supply (SMPS) applications. The devices meet market needs for performance, ease-of-use and price-to-performance ratio, and focus on flyback applications such as adapter and charger, LED driver, audio SMPS, AUX and industrial power. The devices offer up to 0.6 percent efficiency gain and 2C to 8C lower MOSFET temperature compared to similar parts tested in typical flyback applications. The family achieves this performance by reducing Eoss and Qg by over 50 percent, as well as reductions in Ciss and Coss. The devices also enable higher power density in designs through lower switching losses and exceptional RDS(ON). Overall, the family helps designers save BOM costs and reduce assembly efforts. The devices integrate a Zener diode to significantly improve ESD ruggedness protection up to Class 2 (HBM), which helps reduce ESD-related production yield losses. The devices are easy to drive and to design-in due to best-in-class gate threshold voltage of 3V and the smallest gate threshold voltage variation of only ± 0.5V. The devices are now stocked in an assortment of packages with on-resistances of 280, 450, 1400, and 4500mOhms to fully address target applications.
