Other Parts Discussed in Thread: LM74700-Q1
Thanks for designing the TIDA-00281. I have a question on the TVS selection. SMBJ28A-13-F was selected for D1 and SMBJ14A-13-F was selected for D2. I checked the TVS datasheet and found out that the peak pluse current Ipp for SMBJ28A-13-F is 13.2A and for SMBJ14A-13-F is 25.8A. I believe the current for the system is more than 20.8A (1000W/48V). That means that Ipp of D1 is below maximum surge current. Did I miss anything? I will appreciate if you could explain whether it is a typo.
Thanks and I look forward to hearing from you,
