Infineon Technologies has extended its existing portfolio of CoolMOS technologies with the 600 V CoolMOS P7 and 600 V CoolMOS C7 Gold (G7) series. The product families are designed to operate at 600V breakdown voltage and deliver improved superjunction MOSFET performance. They achieve unmatched power density in their respective target applications.

600 V CoolMOS P7: Optimized combination of high efficiency and ease-of-use

The newly introduced P7 offers an excellent ease-of-use in the design-in process with benchmark efficiency and optimized price/performance ratio. The device is targeting applications such as chargers, adapters, lighting, TV, PC power, solar, server, telecom and EV charging. It is addressing power classes from 100 W to 15 kW. The 600 V CoolMOS P7 enables efficiency gains of up to 1.5% in the various topologies, and offers up to 4.2°C thermal benefits compared to the competition.

The wide R DS(on) range from 37 mΩ to 600 mΩ for both surface mount (SMD) and through hole packages makes the 600 V CoolMOS P7 suitable for a broad variety of applications and power ranges. In addition, an excellent ESD robustness of more than 2 kV (HBM) protects the device from electro static discharge damage in production, thus offering higher manufacturing quality. Finally, the rugged body diode protects the device during hard commutation events in LLC circuits.

600 V CoolMOS C7 Gold: Best-in-class FOM in innovative SMD TO-Leadless package

The G7 features a lower R DS(on), minimized gate charge Q G, reduced energy stored in the output capacitance, and a 4 pin Kelvin source capability of the TO-Leadless package. This minimizes losses in PFC and LLC circuits and offers a performance gain of 0.6% as well as higher full load efficiency in PFC circuits. The low parasitic source inductance of 1nH also contributes to the increased efficiency levels.

The improved thermal properties in a TO-Leadless package enable the usage in higher current designs while SMD technology allows for a less costly mounting process. Furthermore, the 600 V CoolMOS C7 Gold features the world’s lowest R DS(on), ranging from 28 mΩ to 150 mΩ. Compared to traditional D²PAK, it offers 30% footprint, 50% height and 60% space reduction. Combined, these properties make the device a perfect choice for the realization of highest efficiency and benchmark power density in server, telecom, industrial and solar applications.

Both 600V CoolMOS P7 & C7 Gold series are available in high quantities, and samples can be ordered. For full series datasheets, click here for the C7 series and here for the P7.
