Applications
Description
■ AC ON/OFF static switching in appliances and
industrial control systems
The ACS102-6T belongs to the AC line switch
family. This high performance switch can control a
load of up to 0.2A.
■ Drive of low power high inductive or resistive
loads like:
– relay, valve, solenoid,
– dispenser, door lock
– micro-motor
The ACS102-6T switch includes an overvoltage
crowbar structure to absorb the overvoltage
energy, and a gate level shifter driver to separate
the digital controller from the main switch. It is
triggered with a negative gate current flowing out
of the gate pin.
Benefits
■ Needs no external protection snubber or
varistor.
Functional diagram
■ Enables equipment to meet IEC 61000-4-5.
■ Reduces component count by up to 80%.
■ Interfaces directly with the micro-controller.
OUT
■ Common package tab connection supports
connection of several alternating current
switches (ACS) on the same cooling pad.
■ Integrated structure based on ASD(1)

AC line switch - basic application
The ACS102-6T switch is triggered by a negative gate current flowing from the gate pin G. The
switch can be driven directly by the digital controller through a resistor as shown in Figure 13.
Thanks to its overvoltage protection and turn-off commutation performance, the ACS102-6T
switch can drive a small power high inductive load with neither varistor nor additional turn-off
snubber.

2.1
Protection against overvoltage: the best choice is ACS
In comparison with standard triacs, which are not robust against surge voltage, the ACS102-6T
is over-voltage self-protected, specified by the new parameter VCL. This feature is useful in two
operating conditions: in case of turn-off of very inductive load, and in case of surge voltage that
can occur on the electrical network.
2.1.1 High inductive load switch-off: turn-off overvoltage clamping
With high inductive and low RMS current loads the rate of decrease of the current is very low.
An overvoltage can occur when the gate current is removed and the OUT current is lower than
IH.
As shown in Figure 14 and Figure 15, at the end of the last conduction half-cycle, the load
current decreases (1). The load current reaches the holding current level IH (2), and the ACS
turns off (3). The water valve, as an inductive load (up to 15 H), reacts as a current generator
and an overvoltage is created, which is clamped by the ACS (4). The current flows through the
ACS avalanche and decreases linearly to zero. During this time, the voltage across the switch is
limited to the clamping voltage VCL. The energy stored in the inductance of the load is
dissipated in the clamping section that is designed for this purpose. When the energy has been
dissipated, the ACS voltage falls back to the mains voltage value (5).

2.1.2 AC line transient voltage ruggedness
The ACS102-6T switch is able to withstand safely the AC line transients 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 shown in Figure 16 is representative of the final ACS102-6T application, and is
also used to test the ACS switch according to the IEC 61000-4-5 standard conditions. Thanks
to the load limiting the current, the ACS102-6T switch withstands the voltage spikes up to 2 kV
above the peak line voltage. The protection is based on an overvoltage crowbar technology.
Actually, the ACS102-6T breaks over safely as shown in Figure 17. The ACS102-6T recovers
its blocking voltage capability after the surge (switch off back at the next zero crossing of the
current).
Such non-repetitive tests can be done 10 times on each AC line voltage polarity.
