Infineon Technologies AG introduces the 750V G1 discrete CoolSiC™ MOSFET to meet the increasing demand for higher efficiency and power density in industrial and automotive power applications. The product family includes both industrial-graded and automotive-graded SiC MOSFETs that are optimized for totem-pole PFC, T-type, LLC/CLLC, dual active bridge, HERIC, buck/boost, and phase-shifted full bridge topologies. The MOSFETs are ideal for use in both typical industrial applications, such as electric vehicle charging, industrial drives, solar and energy storage systems, solid state circuit breaker, UPS systems, servers/ datacenters, telecom, and in the automotive sector, such as onboard chargers, DC-DC converters, and many more.

The CoolSiC MOSFET 750 V G1 technology features excellent RDS(on) x Qfr and superior  RDS(on) x Qoss figure-of-merits, resulting in ultra-high efficiency in hard-switching and soft-switching topologies respectively. Its unique combination of high threshold voltage (VGS(th), Typ. of 4.3 V) with low QGD/QGS ratio ensures high robustness against parasitic turn-on and enables unipolar gate driving, leading to increased power density and low cost of the systems. All devices use Infineon’s proprietary die-attach technology, which delivers outstanding thermal impedance for equivalent die sizes. The highly reliable gate oxide design combined with Infineon’s qualification standards delivers robust and long-term performance.
