Typical application description
The ACST10 device has been designed to control medium power load, such as AC motors
in home appliances. Thanks to its thermal and turn off commutation performances, the
ACST10 switch is able to drive an inductive load up to 10 A with no turn off additional
snubber. It also provides high thermal performances in static and transient modes such as
the compressor inrush current or high torque operating conditions of an AC motor. Thanks
to its low gate triggering current level, the ACST1010-7 can be driven directly by an MCU
through a simple gate resistor as shown Figure 15.

AC line transient voltage ruggedness
In comparison with standard Triacs, which are not robust against surge voltage, the ACST10
is self-protected against over-voltage, specified by the new parameter V . The ACST10
CL
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 Figure 17 represents the ACST10 application, and is used to stress the
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 ACST10 folds back safely to the on state as shown in Figure 18. The
ACST10 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.
