Infineon adds 400V and 440V CoolSiC MOSFETs
Infineon has expanded its CoolSiC MOSFETs 400V G2 portfolio with the top-side-cooled (TSC) TOLT package as well as the TO-247-3 and TO-247-4 packages.
In addition, three new products in the TOLL package have been introduced, with rated voltages of 440V (continuous) and 455V (transient). The new CoolSiC MOSFETs deliver improved thermal performance, system efficiency, and power density.
They MOSFETs have been designed to meet the requirements of high-power and compute-intensive applications, including AI server power supplies, solar inverters, uninterruptible power supplies, Class D audio amplifiers, motor drives, and solid-state circuit breakers.
Compared to existing silicon technologies in the 250V and 300V voltage classes, CoolSiC G2 400V and 440 V MOSFETs achieve up to 50 percent lower conduction losses at an operating temperature of 120 °C, thanks to their flat R(DS(on) as a function of junction temperature (Tj), according to Infineon. They also feature improved switching figures of merit, resulting in at least five times lower reverse recovery charge.
At the system level, CoolSiC G2 400V and 440V MOSFETs in a three-stage flying-capacitor CCM totem-pole PFC achieved up to 0.4 percentage points higher peak PSU efficiency compared to a state-of-the-art interleaved two-level CCM totem-pole PFC. This translates into approximately 15 percent lower system losses at peak efficiency.
The CoolSiC MOSFET 400V and 440V G2 portfolio is available now.
