MLA Varistor Series
Description
The MLA Series (also known as "ML" series) family of
transient voltage surge suppression devices is based on
the Littelfuse 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 MLA Series is typically applied to protect
integrated circuits and other components at the circuit
board level.
The wide operating voltage and energy range make the
MLA Series suitable for numerous applications on power
supply, control and signal lines.
SizeTable
The MLA Series is manufactured from semiconducting
ceramics, and is supplied in a leadless, surface mount
package. The MLA Series is compatible with modern
reflow and wave soldering procedures.

It can operate over a wider temperature range than Zener
diodes, and has a much smaller footprint than plastic-
housed components.
Littelfuse Inc. manufactures other multilayer series
products. See the MLE Series data sheet for ESD
applications, MHS Series data sheet for high-speed ESD
applications, the MLN Series for multiline protection and
the AUML Series for automotive applications.

Device Characteristics
ClampingVoltage OverTemperature (VC at 10A)
At low current levels, the V-I curve of the multilayer
transient voltage suppressor approaches a linear (ohmic)
relationship and shows a temperature dependent effect.
At or below the maximum working voltage, the suppressor
is in a high resistance modex (approaching 106Ω at its
maximum rated working voltage). Leakage currents at
maximum rated voltage are below 100µA, typically 25µA;ꢀ
for 0402 size below 20µA, typically 5µA.

Energy Absorption/Peak Current Capability
Energy dissipated within the MLA Series is calculated
by multiplying the clamping voltage, transient current
and transient duration. An important advantage of the
multilayer is its interdigitated electrode construction within
the mass of dielectric material. This results in excellent
current distribution and the peak temperature per energy
absorbed is very low. The matrix of semiconducting grains
combine to absorb and distribute transient energy (heat)
(see Speed of Response). This dramatically reduces peak
temperature;ꢀthermalꢀstressesꢀandꢀenhancesꢀdeviceꢀ
reliability.

Speed of Response
The Multilayer Suppressor is a leadless device. Its
response time is not limited by the parasitic lead
inductances found in other surface mount packages.
The response time of the ZNOꢀdielectricꢀmaterialꢀisꢀlessꢀ
than 1ns and the MLA can clamp very fast dV/dT events
such as ESD. Additionally, in "real world" applications,
the associated circuit wiring is often the greatest
factor effecting speed of response. Therefore, transient
suppressor placement within a circuit can be considered
important in certain instances.
As a measure of the device capability in energy and peak
current handling, the V26MLA1206A part was tested with
multipleꢀpulsesꢀatꢀitsꢀpeakꢀcurrentꢀratingꢀ(3A,ꢀ8/20µs). At
the end of the test,10,000 pulses later, the device voltage
characteristics are still well within specification.

Lead (Pb) Soldering Recommendations
Theꢀprincipalꢀtechniquesꢀusedꢀforꢀtheꢀsolderingꢀofꢀ
components in surface mount technology are IR Re-flow
and Wave soldering. Typical profiles are shown on the right.

The recommended solder for the MLA suppressor is
aꢀ62/36/2ꢀ(Sn/Pb/Ag),ꢀ60/40ꢀ(Sn/Pb)ꢀorꢀ63/37ꢀ(Sn/Pb).ꢀ
Littelfuse also recommends an RMA solder flux.

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 MLA chip is not subjected to a thermal
gradientꢀsteeperꢀthanꢀ4ꢀdegreesꢀperꢀsecond;ꢀtheꢀidealꢀ
gradient being 2 degrees per second. During the soldering
process,ꢀpreheatingꢀtoꢀwithinꢀ100ꢀdegreesꢀofꢀtheꢀsolder'sꢀ
peak temperature is essential to minimize thermal shock.

process and subjected to cleaning solvents at room

Note: the Lead–free paste, flux and profile were used for
evaluation purposes by Littelfuse, based upon industry
standards and practices. There are multiple choices of all
three available, it is advised that the customer explores the
optimum combination for their process as processes vary
considerably from site to site.
