Part Number: TIDA-01604
Recently I learned about the TIDA-01604, and I have some questions.
This design is a bridgeless power factor correction (PFC) solution, what's the role of the D102(FET Paralled Rectifier).
Shall we use the SiC MOSFET C3M0065100K or C3M0030090K to take the place of the C2M0025120D(Q7-Q10).
The D102 rectifier is for inrush current control for protecting the MOSFET body diode.
Yes, you may. Just keep in mind that the higher the Rdson MOSFET being used, the higher the conduction losses are, which eventually decrease the efficiency.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Xun:
Thanks, I comprehend the function of the D102 rectifier.
And I wonder that if the Vds and Id (except Rdson) should be consider when we use the MOSFET C3M0030090K(900V, 63A) or C3M0065100K(1000V, 35A) to take the palce of C2M0025120D(1200V, 90A).
I'm still a little confused about the device selection.
And I hope to hear from you soon.
In reply to user6093878:
it is ok to replace the C2M0025120D with C3M0030090K. The RMS current flowing into the LF MOSFET bridge is about 32A. C3M0065100K is too less.
OK，I see that.
Thank you very much!
