600 V CoolMOS™ PFD7

600 V CoolMOS™ PFD7

The latest 600 V CoolMOS™ PFD7 series sets a new benchmark in 600 V superjunction (SJ) technologies suitable for ultrahigh power density designs like chargers and adapters. This product family offers up to 1.17 % efficiency increase compared to the CoolMOS™ P7 technologies, which leads to a power density increase of 1.8 W. This outstanding improvement is achieved by lower conduction and charge/discharge losses, as well as reduced turn-off and gate-driving losses, enabled by pushing the cutting-edge CoolMOS™ technology to new limits.

700 V CoolMOS™ P7

The 700 V CoolMOS™ P7 offers a price competitive solution for consumer applications such as chargers and adapters in the power range from 10 W to 75 W. In other words, this product addresses the low-power SMPS market where it tackles common barriers through excellent performance and ease-of-use. The named power converters are typically based on flyback topologies. That is why the 700 V CoolMOS™ P7 is no longer a multi-purpose MOSFET, it is now a tailored technology optimized for flyback topologies.

In a SOT-223 package

The 700 V CoolMOS™ P7 is available in the cost-effective SOT-223 package, the perfect drop-in replacement as it fits to common DPAK properties (i.e. smaller footprint while DPAK pin-to-pin compatible) and reduces the overall bill of material (BOM). Improved form factors enable space savings without a significant disadvantage in thermals. The CoolMOS™ P7 in SOT-223 is Infineon’s contribution to the design of competitive products that match the increasing demand for compact, light and slim low power SMPS designs.

600 V/650 V CoolMOS™ C7

600 V/650 V CoolMOS™ C7

The 600 V and 650 V CoolMOS™ C7 superjunction MOSFET series are designed to achieve record level efficiency performance. They offer substantial efficiency benefits over the whole load range in hard-switching applications compared to previous series and competition. This is achieved by minimizing switching losses via ultralow levels of switching losses (EOSS) (approximately 50 percent reduction compared to the CoolMOS™ CP), reduced gate charge (QG), and a careful balance of other relevant product key parameters. The low EOSS and QG also enable operation at higher switching frequency and related size reduction of the circuit magnetics.

OptiMOS™ PD power MOSFETs

Low- and medium voltage MOSFETs: OptiMOS™ PD 25 – 150 V

OptiMOS™ PD is Infineon‘s new power MOSFET portfolio representing the best fit for USB-PD and fast charger designs, supporting short lead times as well as fast quote response times.

The logic level OptiMOS™ PD power MOSFETs in PQFN 3.3 x 3.3 and in SuperSO8 packages have been optimized for synchronous rectification in charger and adapter SMPS applications. Hence, they are highly suitable for addressing the requirements of USB PD charger and adapter designs. Small package sizes translate into shrunk form factors. Lower charges for reduced switching losses and an excellent price/performance ratio lead to system BOM cost improvements. The logic level drive provides a low gate threshold voltage (VGS(th)) allowing the MOSFETs to be driven from 4.5 V or directly from microcontrollers leading to a lower part count in the application. Low reverse-recovery charge (Qrr) and output charge (Qoss) yield low overshoot in synchronous rectification.
