At the end of the last conduction half-cycle, the load current reaches the holding current level I
H
, and the
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
CL
.
The energy storedintheinductance ofthe loaddepends ontheholding current I
H
and theinductance(up to
10 H);it canreach about20mJ andis dissipatedinthe clamping section thatis especiallydesigned for that
purpose.
The ACS108 switch is able to sustain safely the AC line transient voltages either by clamping the low en-
ergy spikes or by breaking over under high energy shocks, even with high turn-on current rises.
The test circuit ofthe figure4 isrepresentative ofthe final ACS
application and is also used to stressthe
ACS
switch according to the IEC1000-4-5 standard conditions. Thanks to the load, the ACS
switch
sustains the voltagespikes upto 2kV abovethepeak linevoltage. Itwill breakover safelyeven onresistive
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.
