Notes :
This peak current is the maximum peak current in which the nominal
varistor voltage shift does not exceed ±10% when the test impulse is
applied twice at 5 mimutes intervals.
①The waveform of the maximum DC applied voltage is flat. When a ripple
voltage as from a rectifier source is supplied make sure that the peak
voltage is kept under th Vdcm
④Nominal varistor voltage : Vnom
An AC applied voltage(50/60Hz) form a since waveshape.
When the distortion in the waveform is extensive make sure that the
Indicates the varistor terminal voltage measured with a 1mA DC applied.
-0.1mA DC in the case of the 0.5A and 05B series.
⑤Maximum clamping voltage : Vc
Indicates the peak teminal voltage measured with an 8/20㎲ impulse
current applied.
peak voltage is less than
②Energy : Wtm
√
2times the Vacm.
Transient energy ratings are given in the Wtm column of the
specifications in Joules (watt-second).
The rating is the maximum allowable energy for a single impulse of 2ms
square-waveform current with continuous voltage applied. Energy
ratings are based on a shift of Vnom of less than ±10% of initial value.
③Transient peak current (ltm)
The peak current rating. ltm. of varistor is based on an 8/20㎲ test
impulse waveshape.

The varistor SVC has a capacitance value. Take not of this when
applying them to high-frequency signal circuits.
Notes :
①The power supply voltage must not exceed the maximum
allowable circuit voltage.
②Since independent wiring loads and capacitive loads cause the
voltage build-up at the time of opening or closing the load, use SVC
having a varistor voltage as high as possible.(ꢂmark)
③The bold faced portions of the type letters vary.

①When subjected to megger testing (500V DC), the insulation
resistance value can decrease due to the leakage current of the
SVC, To avoid this remove the varistor or useꢂ marked SVC.
②When subjected to dielectric strength test(1000V AC). remove the
SVC or useꢂꢂ marked SVC.

①The power supply voltage must not exceed the maximum
allowable circuit voltage of the SVC
②Pay due attention to the surge energy generated by the load.
③Select SVC referring to the pulse lifetime rating.
④To further reduce the tendency of sparking across the contacts
connect a capacitor parallel with the SVC. This will also protect the
equipment from electromagnetic wave jamming.

■ Application notes
1. Overcurrent protection
2.Installation
When surges exceed the rating for the SVC, short-circuits or
damages can be expected. Take following precautions.
① When operated at location near heating element or exp-
osed to direct sun light, confirm that the the ambient
temparature range.
② When operated in dusty or dirty locations, or exposed to
corrosive atomospheres, or where metallic powders or salt
can be expected, be sure to mount within a protective enclo-
sure.
3. Molding
When shielding the SVC in a resin molding, take a note of the
materials used and temperature, since they influence the
reliability. For further information please contact SAMWHA
4.Current, power and energy rating vs, temperature
① Connect the SVC at a position nearer to the equipment
than the overcurrent protection device“Ⅰ”(fuse, MCCB) as is
shown in the diagram.
When the SVC is shorted, the overcurrent protection device
“Ⅰ”operates (trips or blow off the fuse).
② If the overcurrent protection device“Ⅰ”can not be in-
stalled in“Ⅰ”position, connect a fuse at“Ⅱ”position. Select
fuse rated current for the SVC referring to the following table.

Varistor Terminology
ꢀVaristor Voltage : Vnom
ꢀRated transient energy : Wtm
ꢀTset current waveform
Varistor peak terminal voltage
measured with a specified current
applied
The DC current applied is 1mA
normally.
Maximum allowable energy for a
single impulse of 2ms square-wave
current waveform with rated contin-
uous voltage applied. Maximum
energy rating base on a shift of
Vnom of less than ±10% of initial
value.
Characteristics tests for Varistors
are carried out by using 8/20㎲ test
impulses Data such as the
maximum clamping voltage(Vc)and
the transient peak current(ltm) are
obtained by using this impulse
current.
However, for the Vc characteristics
of the Axial package type a 10mA
DC squarewave current is used to
cary out the test.
ꢀPulse lifetime rating
ꢀClamping voltage : Vc
This is expressed as the maximum
allowable number of impulse curr-
ents applied.
8/20㎲ impulse current (or 2ms sq-
uare wave) is applied at prescribed
interval.
Maximum terminal voltage (peak
voltage across the varistor)
measured with an applied 8/20㎲
impulse of a given peak current.
ꢀRated RMS Voltage : Vacm
Maximum continuous sinusoidal
RMS voltage at 50/60Hz which
may be applied.
This curve also provides for
derating current as required with
repetitive pulsing.
ꢀRated DC Voltage : Vdcm
Maximum continuous DC voltage
which may be applied.
ꢀRated average power dissipation
: Ptam
Maximum average power that can
be applied within the specified
ambient temperature.
ꢀCapacitance
Typical values measured at a test
frequency of 1kHz
ꢀRated peak transient current
: itm
Maximum peak current through the
varistor with line voltage applied.
The maximum peak current with in
the varistor voltage change ratio of
±10% with the standard 8/20㎲
impulse current applied two times
at 5 minute interval.
