High Surge Suppression Varistors
FEATURES
•
Zinc oxide disc, epoxy coated
•
Straight or kinked leads.
APPLICATION
•
Supression of transients
DESCRIPTION
The varistors consist of a disc of low-ß ceramic material with
two tinned solid copper leads. They are coated with a layer of
ochre coloured epoxy, which provides electrical, mechanical
and climatic protection. The encapsulation is resistant to all
cleaning solvents in accordance with
“IEC 60068-2-45”
.

MOUNTING
The varistors are suitable for processing on automatic
insertion and cutting and bending equipment.
Varistors with flanged leads provide better positioning on
printed-circuit boards (PCB) and more accurate control over
component height. This is important for hand mounting and
automatic insertion techniques; see Outlines of flanged leads
drawing.
Soldering
240 C; duration 5 s
Resistance to heat
260 C; duration 5 s

1. Lists with products certified according to UL (E98144), VDE (40002622) and CSA (219883) are available at www.vishay.com or on request.
2. The sinusoidal voltage is assumed as the normal operating condition. If a non-sinusoidal voltage is present, type selection should be based
on multiplying the peak voltage by a factor of 0.707.
3. The voltage measured at 1 mA meets the requirements of
“paragraph 4.3 of CECC specification 42000”
.
The tolerance on the voltage at 1 mA is
±
10%.
4. High energy surges are generally of longer duration. The maximum energy for one pulse of 10
×
1000
µ
s is given as a reference for longer
duration pulses. This pulse can be characterised by peak current (I
p
) and pulse width t
2
(virtual time of half I
p
value, following
“IEC 60060-2,
section 6”
). If V
p
is the clamping voltage corresponding to I
p
, the energy absorbed in the varistor is determined by the formula:
E
=
K
×
V
p
×
I
p
×
t
2
where:
a) K is dependant on the value of t2 when the value of t1 is between 8 µs and 10 µs; see Peak Current as a Function of Pulse Width drawing.
5. A current wave of 8 x 20 µs (requirement of
“paragraph B.2.10.1 of CECC specification 42000”
) is used as a standard for pulse current and
clamping voltage ratings. The maximum non-repetitive transient current is given for one pulse applied during the life of the component.
