Next-Gen CoolSiC G2 MOSFETs from Infineon Enhance Power Density for Industrial Applications

Infineon just introduced a new generation of CoolSiC™ MOSFETs rated for 1200 V, now available in a Q-DPAK package that allows cooling by letting heat escape from the top. These devices are tweaked to suit the demands of industrial applications like EV chargers, solar inverters, UPS systems, motor drives, and solid-state circuit breakers. 

When compared to older versions, these new MOSFETs reduce switching losses by 25%. They make use of Infineon’s enhanced .XT™ interconnect tech to cut down thermal resistance by over 15%, effectively enabling improved system efficiency and power density. The MOSFETs feature RDS(on) values between 4 mΩ and 78 mΩ, making things flexible for a wide range of system designs. Further, they support high junction temperatures (up to 200°C) and offer a strong resistance to parasitic turn-on, improving reliability under high-stress conditions.

Package types in the TSC platform share a standard height of 2.3 mm, including TOLT and Q-DPAK, simplifying thermal design under a shared heatsink. The package is compatible with automated manufacturing processes, making production simple and keeping costs to a minimum. The IMCQ120R026M2H CoolSiC MOSFET is now available in both Q-DPAK single-switch and dual half-bridge variants.
