AC line transient voltage ruggedness
In comparison with standard Triacs, which are not robust against surge voltage, the ACST6
is self-protected against over-voltage, specified by the new parameter V
switch can safely withstand AC line transient voltages either by clamping the low energy
spikes, such as inductive spikes at switch off, or by switching to the on state (for less than 10
ms) to dissipate higher energy shocks through the load. This safety feature works even with
high turn-on current ramp up.
The test circuit of
ACST switch according to the IEC 61000-4-5 standard conditions. With the additional effect
of the load which is limiting the current, the ACST switch withstands the voltage spikes up to
2 kV on top of the peak line voltage. The protection is based on an overvoltage crowbar
technology. The ACST6 folds back safely to the on state as shown in
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 on each AC line voltage polarity.
