Hi Luo,

Welcome to TI E2E forum!

Surge test for the isolation barrier is a destructive test. If the device's isolation barrier is intact after the surge test, it is considered a pass. You can verify if the isolation barrier is intact by checking its isolation resistance RIO. RIO of a working isolation barrier should be >10^9 as stated in the datasheet insulation specifications table.

Let me know if you have any further questions, thanks.
