Description
The ACST1635-8FP belongs to the AC power
switch range built with A.S.D. technology. This
®
high performance device is designed for home
appliances or industrial systems and drives loads
up to 16 A.
– Solid state relays
This ACST1635-8FP switch embeds a Triac
structure with a high voltage crowbar device to
absorb the inductive turn-off energy and
withstand line surges such as those described in
the IEC 61000-4-5 (surge immunity test).

Typical application descriptions
The ACST1635-8FP device can be used to control medium power load, such as AC motors
in home appliances. Thanks to its thermal and turn off commutation performances, the
ACST1635-8FP switch is able to drive an inductive load up to 16 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.

AC line transient voltage ruggedness
In comparison with standard Triacs, which needs additional protection components against
surge voltage, the ACST1635-8FP is self-protected against over-voltage, specified by the
new parameter V . The ACST1635-8FP switch can safely withstand AC line transient
CL
voltages either by clamping the low energy spikes, such as the 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 19 represents the ACST1635-8FP 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 ACST1635-8FP folds back safely to the on state as
shown in Figure 20. The ACST1635-8FP recovers its blocking voltage capability after the
surge and the next zero crossing current. Such a non repetitive test can be done at least 10
times on each AC line voltage polarity.
