FAE Expert Insights
"The PSD1-65H040 is a cost-effective SiC diode for medium-power applications. The 40A rating is perfect for 3-7kW PFC circuits where the 60A version would be overkill. I frequently recommend this diode for solar microinverters and small motor drives. The zero reverse recovery provides measurable efficiency improvements even at moderate switching frequencies. The TO-247 package is easy to work with and provides good thermal performance. For designers transitioning from silicon to SiC, this is a good entry point - significant efficiency gains at a moderate cost premium. The 40A rating provides good margin for most medium-power applications."
