Surface Mount Multilayer Varistor
SC0805ML - SC2220ML Series
Description
The SC Series is based on Multilayer fabrication technology.
These components are designed to suppress a variety of
transient events, including those specified in IEC 61000-4-2 or
other standards used for Electromagnetic Compliance (EMC).
The SC Series is typically applied to protect integrated circuits
and other components at the circuit board level. It can operate
over a wider temperature range than zener diodes.
Features
u
u
Rectangle, sizes serialization for hybrid integrated circuit
or printed circuit surface mount components
There are many side electrode lead-out material,
particularly suitable for surface mount technology for
solderability and resistance to soldering heat of the
stringent requirements
u
u
u
Fast response (<1ns)
Low leakage current, low clamping voltage
Suitable for reflow, wave soldering and hot air hand
soldering
Equivalent Circuits

The solder paste shall be printed in a thickness of 150 to 200μm.

The SIR test of the solder paste shall be done (Base on JIS-Z-3284)
l
IR Soldering
Rapid heating, partial heating or rapid cooling will easily cause defect of the component. So preheating and gradual cooling
process is suggested. IR soldering has the highest yields due to controlled heating rates and solder liquidus times. Make sure
that the element is not subjected to a thermal gradient steeper than 4 degrees per second. 2 degrees per second is the ideal
gradient. During the soldering process, pre-heating to within 100 degrees of the solder peak temperature is essential to
minimize thermal shock.
