ACST4 Series® January 2003 - Ed: 3A AC POWER SWITCH DPAK ACST4-7SB/CB n Blocking voltage : VDRM /V RRM = +/-700V n Avalanche controlled : VCL typ = 1100 V n Nominal conducting current : IT(RMS) =4 A n High surge current capability: 30A for 20ms full wave n Gate triggering current : IGT < 10 mA or 25mA n Switch integrated driver n High noise immunity : static dV/dt >500V/µs

FEATURES

The ACST4 belongs to the AC power switch family built around the ASD™ technology. This high per- formance device is adapted to home appliances or inductrial systems and drives loads up to 4 A. The ACS™ switch embeds a Triac structure with a high voltage clamping device to absorb the induc- tive turn-off energy and withstand line transients such as those described in the IEC61000-4-5 stan- dards.

The ACST4 device has been designed to switch on & off low power, but highly inductive or resistive loads such as dishwashers spray pumps, and air-conditioners fan. Pin COM: Common drive reference to connect to the power line neutral Pin G: Switch Gate input to connect to the digital controller Pin OUT: Switch Output to connect to the load ACST4-7S triggering current has to be sunk from the gate pin G. The switch can then be driven directly by logic level circuits through a resistor as shown on the typical application diagram ( Fig A ). Thanks to its thermal and turn off commutation performances, the ACST4 switch is able to drive with no turn off additional snubber an inductive load up to 4 A. AC LINE SWITCH BASIC APPLICATION OUT COM G ACST4 ST72 MCU N AC MAINS L R - Vcc M LOAD OUT L TYPICAL APPLICATION DIAGRAM (Fig. A) The ACST4 switch is able to sustain safely the AC line transient voltages either by clamping the low energy spikes or by breaking over under high energy shocks, even with high turn-on current rises. The test circuit of the figure 2 is representative of the final ACST application and is also used to stress the ACST switch according to the IEC 61000-4-5 standard conditions. Thanks to the load, the ACST switch sustains the voltage spikes up to 2 kV above the peak line voltage. It will break over safely even on resistive load where the turn on current rate of rise, is as high as shown on figure 3. Such non-repetitive test can be done 10 times on each AC line voltage polarity. AC LINE TRANSIENT VOLTAGE RUGGEDNESS
