600V CoolMOS™ G7

Überblick

Infineon Technologies introduces the 600V CoolMOS™ C7 Gold (G7) technology in surface mount device (SMD) with bottom-side cooling TO-Leadless (TOLL). The 600V CoolMOS™ G7 family is now available also in Infineon’s latest top-side cooling package innovation, the Double DPAK (DDPAK) package.

The CoolMOS™ G7 for the first time brings together the benefits of the improved 600V CoolMOS™ C7 technology, 4-pin Kelvin source capability and the improved thermal properties of the TO-Leadless and DDPAK packages to enable an SMD solution for high current hard switching topologies such as power factor correction (PFC) up to 3kW and for 600V CoolMOS™ G7 also for resonant circuits such as high end LLC.

The most notable customer benefits are a higher efficiency due to the improved CoolMOS™ G7 technology, faster switching due to the package low parasitic source inductance and the 4-pin Kelvin source concept, improved power density due to low R_DS(on) in small footprint and production cost reduction through quicker assembly times by moving to SMD.
