The figure below shows how the positively biased SCR handles the surge current, during the surge test at 0°
phase angle.

Waveforms resulting from the 2 kV IEC61000-4-5 test (C and D configurations)
During the IEC 61000-4-5 lightning surge test, the triac, diodes, and SCR measured values are within the
specified values.
Components stay in a safe operating area during the 2 kV IEC61000-4-5 surge test.
