Replacement for 650V CoolMOS™ CFD2 is 600V CoolMOS™ CFD7 650V CoolMOS™ CFD2 is Infineon's second generation of market leading high voltage CoolMOS™ MOSFETs with integrated fast body diode. The CFD2 devices are the successor of 600V CFD with improved energy efficiency. The softer commutation behavior and therefore better EMI behavior gives this product a clear advantage in comparison with competitor parts.
