ACS302-5T3
HIGH INDUCTIVE SWITCH-OFF OPERATION
At the end of the last conduction half-cycle, the load current reaches the holding current level I
ACS™ switch turns off. Because of the inductance L of the load, the current flows through the avalanche
diode D and decreases linearly to zero. During this time, the voltage across the switch is limited to the
clamping voltage V
The energy stored in the inductance of the load depends on the holding current I
10 H); it can reach about 20 mJ and is dissipated in the clamping diode section that is especially designed
for that purpose.

AC LINE TRANSIENT VOLTAGE RUGGEDNESS
The ACS302 switch is able to withstand safely the AC line transient voltages either by clamping the low en-
ergy spikes or by breaking over under high energy shocks.
The test circuit of the figure 3 is representative of the final ACS™ application and is also used to stress the
ACS switch according to the IEC61000-4-5 standard conditions. Thanks to the load, the ACS™ switch
withstands the voltage spikes up to 2 kV above the peak line voltage. It will break over safely even on resis-
tive load where the turn on current rise is high as shown on figure 4. Such non repetitive test can be done
10 times on each AC line voltage polarity.
