Infineon Technologies 650V CoolMOS™ CFD7A SJ Power MOSFETs

Infineon Technologies 650V CoolMOS™ CFD7A SJ Power MOSFETs address electric vehicle applications such as on-board chargers, HV-LV DC-DC converters, and auxiliary power supplies. Thanks to the improved cosmic radiation robustness, the CoolMOS CFD7A SJ Power MOSFETs allow higher battery voltages to be applied at a reliability rate equal to that of previous generations and other market offerings. CoolMOS CFD7A SJ Power MOSFETs ensure high-efficiency levels in hard- and resonant switching topologies, particularly at light load conditions. Higher switching frequencies at gate loss levels comparable to those of former generations are reached. The reduction in system weight and the smaller occupied space result in more compact designs.

The CoolMOS CFD7A SJ Power MOSFETs qualification exceeds the AEC-Q101 automotive reliability standard. The product family represents a scalable and flexible solution that can be used in both PFC and DC-DC stages, as the parts come with an intrinsic fast body diode and a broad portfolio line-up. When housed in the D²PAK 7-pin package featuring the Kelvin-source concept, the CoolMOS CFD7A technology, especially at high currents, generates significant system-level advantages by reducing switching losses and heat.
