DESCRIPTION

The ACST6-7Sx belongs to the AC power switch
family built around the ASD technology. 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.

ACST6-7S

AC LINE SWITCH BASIC APPLICATION

TheACST6-7Sdevice is especially designed todrivemedium power induction motors inrefrigerators,dish
washers, and tumble dryers.

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 flow­ingoutof the gate pin G. Itcanbe directly driven by the controllerthrougha resistor as shown onthetypical
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.

Thankstoits thermal andturn-offcommutation characteristics, theACST6-7Sswitch is ableto drive an
inductive load up to 6A without a turn-off aid snubber circuit.

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 A is representative of the ACST application and is used to test the ACST switch
according to the IEC61000-4-5 standard conditions.Thankstotheloadimpedance,theACSTswitchwith­stands 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.
