Description
The ACS102-6T belongs to the AC line switch family. This high performance switch can control a load of up to 0.2A. 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. Enables equipment to meet IEC 61000-4-5. Reduces component count by up to 80%. Interfaces directly with the micro-controller. Common package tab connection supports connection of several alternating current switches (ACS) on the same cooling pad. Integrated structure based on ASD(a) technology

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. Figure 13. Typical application program

2.1
Protection against overvoltage: the best choice is ACS
In comparison with standard triacs, which are not robust against surge voltage, the ACS1026T 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. Figure 16. Overvoltage ruggedness test circuit Figure 17.
