Infineon adds new packages to CoolSiC MOSFET 750V G2 family
Infineon Technologies AG of Munich, Germany has launched new packages for its CoolSiC MOSFET 750V G2 technology, engineered to deliver the highest system efficiency and power density in automotive and industrial power conversion applications. This latest innovation is now available in a range of packages, including Q-DPAK and D2PAK, offering a portfolio with typical RDS(on) values up to 60mΩ at 25°C.
The portfolio extension includes products for various applications, such as onboard chargers and HV-LV DCDC converters in the automotive sector, and server and telecom SMPS, along with EV charging infrastructure in industrial applications. The ultra-low RDS(on) values of 4mΩ enables applications that require exceptional static-switching performance, such as eFuse, high-voltage battery disconnect switches, solid-state circuit breakers, and solid-state relays. This performance enables designers to create more efficient, compact and reliable systems that meet the most demanding requirements.
A key feature of CoolSiC MOSFET 750V G2 technology is its top-side-cooled Q-DPAK package, which provides optimal thermal performance and reliability. This package is designed to handle high-power applications with ease, making it suitable for designers seeking to push the boundaries of power density and efficiency. The technology also exhibits what is claimed to be excellent RDS(on) x QOSS and best-in-class RDS(on) x Qfr, contributing to reduced switching loss in both hard-switching and soft-switching topologies with superior efficiency in hard-switching user cases.
Additionally, the CoolSiC MOSFETs 750V G2 offer a combination of high threshold voltage VGS(th),typ of 4.5V at 25°C and ultra-low QGD/QGS ratio, reinforcing robustness against parasitic turn-on (PTO). Furthermore, the technology allows for extended gate driving capabilities, supporting static gate voltages of up to –7V and transient gate voltages of up to –11V. This enhanced voltage tolerance provides engineers with greater design margins and best compatibility with other devices in the market.
Samples of the CoolSiC MOSFET 750V G2 Q-DPAK 4/7/20/33/40/50mΩ and D2PAK 7/25/33/40/50/60mΩ are available now.
