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. ## ~~**Size Table**~~ **Metric EIA** 1005 0402 1608 0603 2012 0805 3216 1206 3225 1210 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 plastichoused 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. ## ~~**Absolute Maximum Ratings** 7,~~ ## ~~**Features**~~ • For ratings of individual members of a series, see device ratings and specifications table. - Rated for surge current (8 x 20 _µ_ s) - Halogen-Free and RoHS compliant - ~~a~~ **Continuous ML Series Units** RoHS compliant current (8 x 20 _µ_ s) **Steady State Applied Voltage** • Leadless 0402, • Rated for energy - DC Voltage Range (VM(DC)) 3.5 to 120 V 0603, 0805, 1206 (10 x 1000 _µ_ s) AC Voltage Range (VM(AC)RMS) 2.5 to 107 ~~|~~ V and 1210 chip sizes • Inherent bi-directional **Transient** • Multilayer ceramic clamping - Non-Repetitive Surge Current, 8/20µs Waveform, 4 to 500 A construction • Standard low (ITM) technology capacitance Non-Repetitive Surge Energy, 10/1000µs Waveform, 0.02 to 2.5 J • -40ºC to +125ºC types available (WTM) operating temp. range Operating Ambient Temperature Range (TA) -40 to +125 ºC • Operating voltage range VM(DC) = -40 to 3.5V to 120v - Storage Temperature Range (TSTG) +150 ºC Temperature Coefficient ( α V) of Clamping Voltage <0.01 %/º C ~~**Applications**~~ (VC) at Specified Test Current - ~~—_- Lo~~ • Suppression of • Provides on-board inductive switching transient voltage - **Additional Information** or other transient protection for ICS events such as EFT and transistors and surge voltage at • Used to help achieve the circuit board level electromagnetic - • ESD protection for compliance of - a IEC 61000-4-2, MILend products - **Datasheet Resources Samples** STD-883 method • Replace larger surface 3015.7, and other mount TVS Zeners in industry specifications many applications (see also the MLE or MLN Series) © 2020 Littelfuse, Inc.

At or below the maximum working voltage, the suppressor is in a high resistance modex (approaching 10[6] Ω at its maximum rated working voltage). Leakage currents at maximum rated voltage are below 100 _µ_ A, typically 25 _µ_ A; for 0402 size below 20 _µ_ A, typically 5 _µ_ A. **==> picture [243 x 159] intentionally omitted <==** **----- Start of picture text -----**

## ~~**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 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. **==> picture [187 x 147] intentionally omitted <==** **----- Start of picture text -----**

## ~~**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; thermal stresses and enhances device reliability. 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 (3A, 8/20 _µ_ s). At the end of the test,10,000 pulses later, the device voltage characteristics are still well within specification. ## **Repetitive Pulse Capability** **==> picture [227 x 115] intentionally omitted <==** **----- Start of picture text -----**

Typical profiles are shown on the right. The recommended solder for the MLA 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. 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 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 50º C before cleaning. ## ~~**Refow Solder Profle**~~ **==> picture [243 x 150] intentionally omitted <==** **----- Start of picture text -----**

## ~~**Lead–free (Pb-free) Soldering Recommendations**~~ Littelfuse offers the Nickel Barrier Termination option (see "N" suffix in Part Numbering System for ordering) for the optimum Lead–free solder performance, consisting of a Matte Tin 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. 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. ## ~~**Lead–free Re-fow Solder Profle**~~ **==> picture [243 x 154] intentionally omitted <==** **----- Start of picture text -----**
