This high performance device is adapted to home appliances or industrial systems and drives an induction motor up to 6A. This ACST 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 IEC61000-4-5 standards.

Pin COM : Common drive reference, to be connected to the power line neutral Pin G : Switch Gate input to be connected to the controller Pin OUT : Switch Output to be connected to the load When driven from a low voltage controller, the ACST switch is triggered with a negative gate current flowing out of the gate pin G. It can be directly driven by the controller through a resistor as shown on the typical application diagram. In appliance systems, the ACST6-7S switch intends to drive medium power load in ON / OFF full cycle or phase angle control mode. Thanks to its thermal and turn-off commutation characteristics, the ACST6-7S switch is able to drive an inductive load up to 6A without a turn-off aid snubber circuit. Figure 2: Typical Application Diagram Run Start Run Start OUT OUT G G COM COM ST 62/72 MCU ST 62/72 MCU AC LINE TRANSIENT VOLTAGE RUGGEDNESS The ACST6-7S switch is able to safely withstand the AC line transient voltages either by clamping the low energy spikes or by breaking over under high energy shocks. The test circuit in figure 3 is representative of the ACST application and is used to test the ACST switch according to the IEC61000-4-5 standard conditions. Thanks to the load impedance, the ACST switch withstands voltage spikes up to 2 kV above the peak line voltage by breaking over safely. Such non-repetitive testing can be done 10 times on each AC line voltage polarity.
