DESCRIPTION
The LVS series is metal oxide based chip varistor for transient
voltage suppression. They have non-linear voltage-current
behavior, similar to zener diode. Multilayer structured varistor,
however, shows superiority in electrical reliability than zener
diode, since each grain exhibits small p-n junction. In addition,
LVS series shows better electrical properties such as high
clamping voltage and low leakage current.
FEATURES
APPLICATIONS
*Chip varistor provides high reliability on surface mounting

*Replacement of zener diode
W
*Wide range of working voltage (V = 5.6V˜30V)
*Good clamping ratio and low leakage current
*Electroplating of Ni and solder gives higher solderability

APPLICATION FOR ESD
What is ESD ?
Protection Performance of Lattron is Varistor for ESD
It is a kind of transient voltage noise. The definition of transient
voltage is listed in IEC 61000-4 series, which describes the
immunity requirements and test methods for electrical and
electric equipments, subjected to ESD, EFT, and surge. Figure 1
is the waveform of ESD, defined in IEC 61000-4-2.
The performance of Lattron is varistor against ESD noise is
tested with the test circuit as shown in Picture 2.
Test procedure includes three different circuit configurations;
without varistor, with varistor at DUT position, and shorted circuit
at DUT position. The test results that had collected with digital
scope are shown in Picture 3.
The performance of ESD suppression with Lattron is varistor is
as good as that of short circuit.
Picture 2.
Picture 1.
Varistor vs. TVS Diode
ESD current has the rise time of sub-nanosecond, duration of
tens of nanosecond, and its amplitude reaches over 10KV. So,
the protecting device from ESD also needs fast response time.
TVS diode has a similar performance with that of LATTRON's
varistor, in terms of response time and handling capacity. Which,
however, shows inferiority in surge current, leakage current,
operating directionality, polarity, and miniaturization as shown in
the table.
