I am designing a switch-mode welding power supply. The secondary current is 130 A at 24 V max and the switching frequency is 20 kHz. Using Schottky diodes for full bridge rectification results in around 500 W power dissipation whereas our max power is 3500 W. Also, the diodes for this rating are expensive so cost is an issue.
The diode I was considering before going for alternatives https://media.digikey.com/pdf/Data%20Sheets/International%20Rectifier%20PDFs/UFB200FA20.pdf
I was looking for an active rectification solution and the appropriate MOSFETs are IRFP3206. While looking into the datasheet I found out the body diode of MOSFET is rated for 200 A Continuous Source Current (as the diode is connected to the source). Reverse Recovery Time is 33 ns typ. Maximum Reverse Recovery Current, IRRM is 2.5 A (I don't know what that means).
The question is can I use these diodes for normal rectification? And if I were to use these MOSFETs for active rectification what properties should I be aware of about these body diodes?
The datasheet link is below and a graph about the body diode is included in the datasheet (Fig 21) https://www.infineon.com/dgdl/irfp3206pbf.pdf?fileId=5546d462533600a401535628d64a1ff0.
