Infineon introduces 75mΩ industrial CoolSiC MOSFETs 650V G2 for medium-power applications with high power density
Infineon Technologies AG Munich, Germany is expanding its CoolSiC MOSFETs 650V G2 portfolio with new 75mΩ variants to meet the demand for more compact and powerful systems.
The devices are available now in multiple package options, including TOLL, ThinTOLL 8x8, TOLT, D2PAK, TO247-3 and TO247-4. The product family hence supports both top-side cooling (TSC) and bottom-side cooling (BSC) approaches and offers developers a high degree of flexibility.
The devices are suitable for high- and medium-power switching-mode power supplies (SMPS) in different applications, including AI servers, renewable energy, electric vehicle and e-mobility chargers, humanoid robot chargers, televisions, and drives.
The CoolSiC MOSFETs 650V G2 are based on the second-generation (G2) of CoolSiC technology and offer improved figures of merit, higher reliability, and enhanced ease of use compared with the previous generation.
The different packages offer various advantages: TOLL and ThinTOLL 8x8 packages provide high thermal-cycle stability on the PCB and enable compact system designs. When used in SMPS, they reduce the space requirements on the PCB and lower manufacturing costs at the system level. The list of target applications for TOLL and ThinTOLL 8x8 has been expanded, enabling PCB designers to address cost-reduction challenges.

The addition of TOLT strengthens Infineon's growing TSC product family, which also includes CoolMOS 8, CoolSiC, CoolGaN and Optimos. The TSC variants allow up to 95% direct heat dissipation and enable designers to use both sides of the PCB, improving space utilization and reducing parasitic effects.
