ZHCU763 March 2021
The board is tested for surge voltage up to 1.2 kV with a 12-Ω line impedance. The testing is done with the MOV - ZV40K2220102NIR1HT, connected across the SSR terminal (between the drain of top FET and drain of bottom FET). During the testing the TVS was not mounted. No failure was observed during testing and the SSR worked as usual after surge testing up to 1.2 kV
