Power MOSFETs from Texas Instruments for applications in networking, telecom, and computing systems

DualCool™ NexFET™ CSD16 Q5C MOSFETsTexas Instruments' DualCool NexFET family of power MOSFETs delivers an industry standard footprint, while enabling thermally efficient cooling through the top and bottom of the package. This package allows power system designers to effectively direct heat away from the PCB in high-current DC/DC applications, resulting in improved power density, higher current capability, and improved system reliability. This series is capable of up to 80% more power dissipation, which allows up to 50% more current through the MOSFETs. Topside cooling is enabled by reducing thermal resistance by a factor of ten over conventional packages.
