Hi,
Good Day. I would like to confirm if the devices below can support 230V AC line surge protection for PWM Power Supply Unit.

https://www.ti.com/product/TVS1400
The PWM PSU is fitted with a TOP247YN Controller (per its datasheet to withstand a 700V surge and it failed to protect the PWM PSU, unfortunately) that was dematerialized during a thunder storm damaging other components down the circuit including AN2003B's among others. The PSU was protected with varistors that failed to do the job. If the devices above not fit on the query mentioned, My question is what would you suggest as a reliable protection against HV line surges. The line voltage is 230V AC as mentioned before.
Best Regards,
Ray Vincent
