Thermal management of the present-day SMD-based SMPS designs still remains a barrier to efficiency. Infineon Technologies AG has offered Double DPAK (DDPAK), the first top-side cooled SMD package, addressing high power applications such as server, telecom, solar and high-end PC power.
This packaging solution enables fast switching and high efficiency in reduced size and weight with a minimised total cost of ownership. The top-side cooled package exceeds the industry’s quality requirements. Thanks to the top-side cooling concept, it further shapes the high power SMPS market.
The features of DDPAK get combined with the benefits of the already existing high voltage technologies of 600V CoolMOS G7 SJ MOSFET and CoolSiC Schottky Diode 650V G6. The thermal decoupling of the printed circuit board and semiconductor enables higher power density or longer system lifetime.
DDPAK offers performance as an SMD alternative for high power SMPS designs. Its four-pin configuration allows for separate pin source-sense to deliver undisturbed signal to the driver. Thus, it provides higher efficiency at full load.
Infineon enables optimised system solutions for high power designs by combining its CoolMOS G7 with CoolSiC G6 and EiceDRIVER families. 600V CoolMOS G7 SJ MOSFET and CoolSiC Schottky Diode 650V G6 with DDPAK packaging are available now.
