AC line transient voltage ruggedness
In comparison with standard SCRs, the TS110 is self-protected against over-voltage. The
TS110 switch can safely withstand AC line surge voltages by switching to the on state (for
less than 10 ms on 50 Hz mains) to dissipate energy shocks through the load. The load
limits the current through the TS110. The self-protection against over-voltage is based on an
overvoltage crowbar technology. This safety feature works even with high turn-on current
ramp up.

according to the IEC 61000-4-5 standard conditions. The TS110 folds back safely to the on
state as shown
The TS110 recovers its blocking voltage capability after the surge and the next zero current
crossing. Such a non repetitive test can be done at least 10 times.
