The electronics industry is experiencing a significant shift towards more compact and powerful systems. To support this trend and further drive innovation at the system level, Infineon Technologies AG is expanding its portfolio of discrete CoolSiC MOSFETs 650 V with two new product families housed in Q-DPAK and TOLL packages.

These diverse product families, with top- and bottom-side cooling, are based on the CoolSiC Generation 2 (G2) technology and offer significantly improved performance, reliability, and ease of use. The product families target high- and medium-power switched-mode power supplies (SMPS) including AI servers, renewable energy, chargers for electric vehicles, e-mobility and humanoid robots, televisions, drives and solid-state circuit breakers.

The TOLL package offers outstanding Thermal Cycling on Board (TCoB) capability, enabling compact system designs by reducing the printed circuit board (PCB) footprint. When used in SMPS, it can also reduce system-level manufacturing costs. The TOLL package now fits an extended list of target applications, enabling PCB designers to further reduce costs and better meet market demands.

The introduction of the Q-DPAK package complements the ongoing development of Infineon’s new family of Topside Cooled (TSC) products, which includes CoolMOS 8, CoolSiC, CoolGaN and OptiMOS. The TSC family enables customers to achieve excellent robustness with maximum power density and system efficiency at low cost. It also enables direct heat dissipation of 95 percent, allowing the use of both sides of the PCB for better space management and reduction of parasitic effects.
