AC POWER SWITCH
ACST4 SeriesAC POWER SWITCH Blocking voltage: VDRM /VRRM= +/-700V Avalanche controlled: VCL typ= 1100V Nominal conducting current: IT(RMS) =4A High surge current capability: 30A for 20ms full
wave Gate triggering current: IGT<10 mAor 25mA Switch integrated driver High noise immunity: static dV/dt >500V/μs
FEATURESThe ACST4 belongsto the AC power switch family
built around the ASD™ technology. This high per-
formance deviceis adaptedto home appliancesor
inductrial systems and drives loadsupto4A.
The ACS™ switch embedsa Triac structure witha
high voltage clamping deviceto absorb the induc-
tive turn-off energy and withstand line transients
suchas those describedin the IEC61000-4-5 stan-
dards.

PARAMETER DESCRIPTION
ACST4 SeriesThe ACST4 device has been designedto switchon&off low power, but highly inductiveor resistive loads
suchas dishwashers spray pumps, and air-conditioners fan.
Pin COM: Common drive referenceto connectto the power line neutral
PinG: Switch Gate inputto connectto the digital controller
Pin OUT: Switch Outputto connectto the load
ACST4-7S triggering current hastobe sunk from the gate pinG. The switch can thenbe driven directlyby
logic level circuits througha resistoras shownon the typical application diagram( FigA).
Thankstoits thermal and turnoff commutation performances, the ACST4 switchis ableto drive withno
turnoff additional snubberan inductive loadupto4A.
LINE SWITCH BASIC APPLICATION
TYPICAL APPLICATION DIAGRAM (Fig.A)
The ACST4 switchis ableto sustain safely the AC line transient voltages eitherby clamping the low energy
spikesorby breaking over under high energy shocks, even with high turn-on current rises.
The test circuitof the figure2is representativeof the final ACST application andis also usedto stress the
ACST switch accordingto the IEC 61000-4-5 standard conditions. Thanksto the load, the ACST switch
sustains the voltage spikesupto2kV above the peak line voltage.It will break oversafely evenon resistive
load where the turnon current rateof rise,isas highas shownon figure3. Such non-repetitive test canbe
done10 timeson each AC line voltage polarity.
