Infineon Technologies AG introduced new package options for its CoolSiC™ MOSFET 750 V G2 technology, engineered to raise system efficiency and power density in automotive and industrial power conversion. The devices are available in Q-DPAK and D2PAK, with a portfolio offering typical RDS(on) values up to 60 mΩ at 25°C.
The extended lineup targets onboard chargers and HV-LV DCDC converters in automotive, as well as server and telecom SMPS and EV charging infrastructure on the industrial side. Ultra-low RDS(on) of 4 mΩ enables applications demanding exceptional static-switching performance, including eFuse, high-voltage battery disconnect switches, solid-state circuit breakers and solid-state relays—supporting more efficient, compact and reliable system designs.
A key differentiator is the top-side cooled Q-DPAK package, delivering optimal thermal performance and robustness for high-power use cases. The technology also achieves excellent RDS(on) × QOSS and best-in-class RDS(on) × Qfr, reducing switching losses in both hard- and soft-switching topologies and delivering superior efficiency in hard-switching conditions.
CoolSiC MOSFETs 750 V G2 combine a high threshold voltage VGS(th),typ of 4.5 V at 25°C with an ultra-low QGD/QGS ratio to reinforce robustness against parasitic turn-on (PTO). The platform supports extended gate-drive capability with static gate voltages down to -7 V and transient voltages down to -11 V, providing wider design margins and strong compatibility with other devices in the market.
Samples are available now: Q-DPAK in 4/7/20/33/40/50 mΩ and D2PAK in 7/25/33/40/50/60 mΩ.
