Key applications

Making automotive applications more compact and higher performing


High power density for more compact designs

Boosting efficiency to the next level, CoolMOS™ CFD7A shows improvements in hard- and resonant-switched topologies especially in light-load conditions. Higher switching frequencies can be achieved at gate-loss levels comparable to former generations; and this promising combination makes CFD7A one key enabler for decreased system weight and space to achieve more compact designs.

Highest reliability compliant with automotive lifetime requirements, increased design flexibility and scalability

 As a result of improved cosmic-radiation robustness, the CoolMOS™ CFD7A  technology allows applying  higher battery voltages at the same reliability rate as previous generations and other market offerings.

The CFD7A devices can be used in PFC and DC-DC stages thanks to the intrinsic fast body diode and the broad portfolio line-up.

Excellent efficiency and thermal performance

When using Infineon’s 650V CoolMOS™ CFD7A  technology in combination with the D2PAK 7-pin package customers benefit from enhanced efficiency and thermal behavior. As compared to the D2PAK 3-pin, the Kelvin-source concept used in the
D2PAK 7-pin (driver-source pin) overcomes the limitations caused by the source inductance and improves the switching performance. Resulting advantages at system level, especially at high currents, are the reduction of switching losses and heat. Furthermore, the increased creepage distance of 4.2mm between drain and source/gate facilitates device usage for higher battery voltage classes up to 475V.
