ML Varistor Series  
Description  
The 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 ML 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 ML  
Series suitable for numerous applications on power supply,  
control and signal lines.  
The ML Series is manufactured from semiconducting  
ceramics, and is supplied in a leadless, surface mount  
package. The ML 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.

When transients occur in rapid succession, the average  
power dissipation is the energy (watt-seconds) per pulse  
times the number of pulses per second. The power so  
developed must be within the specifications shown  
on the Device Ratings and SpecificationsTable for the  
specific device. For applications exceeding 125°C ambient  
temperature, the peak surge current and energy ratings  
must be derated as shown below.

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 ML 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; thermal stresses and enhances device  
reliability.

Figure 10  
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 ZNO dielectric material is less  
than 1ns and the ML 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  
multiple pulses at its peak current rating (150A, 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  
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

The recommended solder for the ML 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

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.  
RAMP RATE  
<2°C/s  
PREHEAT DWELL  
PREHEAT ZONE

When using a reflow process, care should be taken to  
ensure that the ML 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.

TIME (MINUTES)  
Wave Solder Profile  
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 50º C before cleaning.

Lead–free (Pb-free) Soldering Recommendations  
Littelfuse offers the Nickel BarrierTermination option (see  
"N" suffix in Part Numbering System for ordering) for the  
optimum Lead–free solder performance, consisting of a  
MatteTin outer surface plated on Nickel underlayer, plated  
on Silver base metal.

The preferred solder is 96.5/3.0/0.5 (SnAgCu) with an RMA  
flux, but there is a wide selection of pastes and fluxes  
available with which the Nickel Barrier parts should be  
compatible.  
RAMP RATE

PREHEAT ZONE  
The reflow profile must be constrained by the maximums  
in the Lead–free Reflow Profile. For Lead–free wave  
soldering, the Wave Solder Profile still applies.

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.
