CoolMOS™ Family Selection Guide

Here we provide you help in the selection of the most suitable CoolMOS™ Power MOSFET for your application. The applications have been divided into high power, low power and automotive, because each segment comes with different requirements.









CoolMOS™ for high power SMPS (>150W)

Pushing the edge of silicon MOSFET performance

The CoolMOS™ high power portfolio addresses the complete application landscape across PFC, LLC and ZVS topologies with product families addressing different sub-segments in terms of efficiency and ease-of-use. CoolMOS™ C7, P6 and CFD2 are active and preferred - we recommend our customers to use these parts for new designs (see selection table below, shown in colors). Older CoolMOS™ generations (see selection table below, shown in grey) like C3, CP, C6 and CFD will be continued for an extended period of time and can still be used by customers for new designs. In special cases, their properties offer an excellent fit to a particular design, while for the majority of applications the newer series, such as CoolMOS™ C7, P6 and CFD2, offer higher customer value at lower price.

CoolMOS™ for low power SMPS (<150W)

Efficiency accessible at an attractive price

In low power SMPS, high voltage SuperJunction MOSFETs address applications such as smartphone/tablet chargers, notebook adapters, TV sets and LED lighting. Increasingly, customers replace standard MOSFETs by SuperJunction  MOSFETs in order to benefit from higher efficiency and an attractive cost-down roadmap going forward. In many  designs, a trade-off decision between highest efficiency, good ease-of-use (typically EMI) and an attractive cost position needs to be made.


The CoolMOS™ portfolio for low SMPS offers a number of choices for power engineers:




CoolMOS™ Automotive

600V CoolMOS™ CPA and 650V CoolMOS™ CFDA - automotive technology in pole position

After launching the first series of high voltage automotive MOSFET, the 600V CoolMOS™ CPA series, Infineon has launched its second generation of market leading automotive qualified high voltage MOSFET, the 650V CoolMOS™ CFDA series. The 600V CoolMOS™ CPA portfolio and the broad 650V CoolMOS™ CFDA portfolio provide all benefits of a fast switching SuperJunction MOSFET while fulfilling the enhanced reliability requirements for automotive applications realized with special screening measures in front end and back end as well as qualification compliant to AEC Q100.


The 650V CoolMOS™ CFDA series additionally caters to special application needs with its integrated fast body Diode. This fast body Diode is the key for addressing resonant switching topologies resulting in lower switching losses due to the low gate charge. The softer commutation behavior and consequent reduced EMI appearance gives the 650V CoolMOS™ CFDA series a clear advantage in comparison to competitor parts. Furthermore, limited voltage overshoot during hard commutation of the body Diode enables easier implementation of layout and design. Therefore, the combination of both, the 600V CoolMOS™ CPA and the new 650V CoolMOS™ CFDA technologies are the best choice for switching topologies in automotive applications. 


Common key features CoolMOS™ "A"

  • First 600V/650V automotive qualified high voltage technologies for automotive market
  • Compliant to AEC Q101 standard


Key features 600V CoolMOS™ CPA Applications 600V CoolMOS™ CPA Key features 650V CoolMOS™ CFDA Applications 650V CoolMOS™ CFDA
