Infineon is expanding its portfolio of discrete CoolSiC MOSFETs 650 V with two product families housed in Q-DPAK and TOLL packages.

These families, with top- and bottom-side cooling, 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 Thermal Cycling on Board (TCoB) capability, enabling compact system designs by reducing the PCB footprint. When used in SMPS, it can also reduce system-level manufacturing costs.

Infineon adds to CoolSiC MOSFETs

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  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.
