The circuit models in Figures 16 and 17 represent
the typical ESD testing circuit used for all three
methods. The C
S is initially charged with the DC
power supply when the first switch (SW1) is on.
Now that the capacitor is charged, the second
switch (SW2) is on while SW1 switches off. The
voltage stored in the capacitor is then applied
through R
S, the current limiting resistor, onto the
device under test (DUT). In ESD tests, the SW2
switch is pulsed so that the device under test
receives a duration of voltage.
For the Human Body Model, the current limiting
resistor (R
S) and the source capacitor (CS) are
1.5kan100pF,respectively. ForIEC-61000-4-2,
thecurrentlimitingresistor(R
S) and the source ca-
pacitor (C
S) are 330 an 150pF, respectively.
The higher C
S value and lower RS value in the
IEC61000-4-2 model are more stringent than the
Human Body Model. The larger storage capaci-
tor injects a higher voltage to the test point when
SW2 is switched on. The lower current limiting
resistor increases the current charge onto the
test point.
