MLN SurgeArray™ Suppressor
Description
The MLN SurgeArray™ Suppressor is designed to
help protect components from transient voltages that
exist at the circuit board level. This device provides four
independent suppressors in a single leadless chip in order
to reduce part count and placement time as well as save
space on printed circuit boards.
SurgeArray™ devices are intended to suppress ESD, EFT
and other transients in order to protect integrated circuits
or other sensitive components operating at any voltage
up to 18VDC. SurgeArray™ devices are rated to the IEC
61000-4-2 human body model ESD to help products attain
EMC compliance. The array offers excellent isolation and
low crosstalk between sections.

EIA
The inherent capacitance of the SurgeArray™ Suppressor
permits it to function as a filter/suppressor, thereby
replacing separate Zener/capacitor combinations.

1206
The MLN array is manufactured using the Littelfuse
Multilayer technology process and is similar to the
Littelfuse ML and MLE Series of discrete leadless chips.

Lead (Pb) Soldering Recommendations
The principal techniques used for the soldering of
components in surface mount technology are IR Re-flow
and Wave soldering. Typical profiles are shown on the right.
Reflow Solder Profile
250
200
150
100
The recommended solder for the MLN suppressor is
a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37 (Sn/Pb).
Littelfuse also recommends an RMA solder flux.
MAXIMUM TEMPERATURE
230°C
40-80
SECONDS
ABOVE 183°C
Wave soldering is the most strenuous of the processes.
To avoid the possibility of generating stresses due to
thermal shock, a preheat stage in the soldering process
is recommended, and the peak temperature of the solder
process should be rigidly controlled.

When using a reflow process, care should be taken to
ensure that the MLN chip is not subjected to a thermal
gradient steeper than 4 degrees per second; the ideal
gradient being 2 degrees per second. During the soldering
process, preheating to within 100 degrees of the solder's
peak temperature is essential to minimize thermal shock.

Once the soldering process has been completed, it is
still necessary to ensure that any further thermal shocks
are avoided. One possible cause of thermal shock is hot
printed circuit boards being removed from the solder
process and subjected to cleaning solvents at room
temperature. The boards must be allowed to cool gradually
to less than 50ºC before cleaning.
