Functional diagram OUT Applications G ■ AC on/off static switching in appliances and industrial control systems ■ Driving low power highly inductive loads like solenoid, pump, fan, and micro-motor Description The ACST2 series belongs to the ACS™/ACST power switch family built with A.S.D.® (application specific discrete) technology. This high performance device is suited to home appliances or industrial systems and drives loads up to 2 A. This ACST2 switch embeds a Triac structure with a high voltage clamping device to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standards. The component needs a low gate current to be activated (IGT < 10 mA) and still shows a high electrical noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).

Thanks to its high sensitivity (IGT max = 10 mA), the ACST2 can be driven directly by logic level circuits through a resistor as shown on the typical application diagram. Thanks to its thermal and turn-off commutation performances, the ACST2 switch can drive, without any additional snubber, an inductive load up to 2 A. Figure 16.

In addition, the ACST2 is a sensitive device (IGT = 10 ma), but provides a high noise immunity level againast fast transients. The ACST2 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 ACST2 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 ACST2 folds back safely to the on state as shown in Figure 18. The ACST2 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.

The intrinsic immunity of the ACST2 is shown by the specified dV/dt equal to 500 V/µs @ 125 °C. This immunity level is 5 to 10 times higher than the immunity provided by an equivalent standard technology Triac with the same sensitivity. In other words, the ACST2 is sensitive, but has an immunity usually available only for non-sensitive device (IGT higher than 35 mA). 8/13 Doc ID 13304 Rev 3 ACST2 3 Ordering information scheme Ordering information scheme Figure 19.
