Chip Varistor
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
*Chip
varistor provides high reliability on surface mounting
*Wide
range of working voltage (V
W
= 5.6V˜30V)
*Good
clamping ratio and low leakage current
*Electroplating
of Ni and solder gives higher solderability
*Wide
operating temperature (-55˜125°C )
*Various
capacitance is available
APPLICATIONS
*Protection
from transient voltage noise in all kinds of IC
*Protection
from ESD, EFT and surge in power I/O port
*Replacement
of zener diode
