39 revised: december 16, 2013 mla varistor series rohs 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 specifed 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. the mla series is manufactured from semiconducting ceramics, and is supplied in a leadless, surface mount package. the mla series is compatible with modern refow 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. features ? rohs compliant ? leadless 0402, 0603, 0805, 1206 and 1210 chip sizes ? multilayer ceramic construction technology ? -55c to +125c operating temp. range ? operating voltage range v m(dc) = 5.5v to 120v ? rated for surge current (8 x 20 s) ? rated for energy (10 x 1000 s) ? inherent bi-directional clamping ? standard low capacitance types available ? esd rated to iec 61000-4-2, level 4: air discharge 15kv and contact discharge 8kv applications ? suppression of inductive switching or other transient events such as eft and surge voltage at the circuit board level ? esd protection for iec 61000-4-2 (level 4), mil-std-883c method 3015.7, and other industry specifcations (see also the mle or mln series) ? provides on-board transient voltage protection for ics and transistors ? used to help achieve electromagnetic compliance of end products ? replace larger surface mount tvs zeners in many applications size table metric eia 1005 0402 1608 0603 2012 0805 3216 1206 3225 1210 absolute maximum ratings for ratings of individual members of a series, see device ratings and specifcations table . continuous ml series units steady state applied voltage: dc voltage range (v m(dc) ) 3.5 to 120 v ac voltage range (v m(ac)rms ) 2.5 to 107 v transient: non-repetitive surge current, 8/20 s waveform, (i tm ) 4 to 500 a non-repetitive surge energy, 10/1000 s waveform, (w tm ) 0.02 to 2.5 j operating ambient temperature range (t a ) -55 to +125 oc storage temperature range (t stg ) -55 to +150 oc temperature coefficient ( v) of clamping voltage (v c ) at specified test current <0.01 %/o c ? 2013 littelfuse, inc. varistor products mla varistor series surface mount multilayer varistors (mlvs) > mla series specifcations are subject to change without notice. please refer to www.littelfuse.com/series/ml.html or mla.html for current information. mla series

44 revised: december 16, 2013 lead (pb) soldering recommendations the principal techniques used for the soldering of components in surface mount technology are ir re-fow and wave soldering. typical profles 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 fux. 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 refow 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. leadCfree (pb-free) soldering recommendations littelfuse offers the nickel barrier termination option (see "n" suffx in part numbering system for ordering) for the optimum leadCfree 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 fux, but there is a wide selection of pastes and fuxes available with which the nickel barrier parts should be compatible. the refow profle must be constrained by the maximums in the leadCfree refow profle. for leadCfree wave soldering, the wave solder profle still applies. note: the leadCfree paste, fux and profle 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. figure 14 . refl ow solder pr ofile figure 15 .w a ve solder pr ofile figure 16 . lead-free re-flow solder pr ofile time (minutes) 30 0 250 20 0 15 0 10 0 50 0 0.0 0.5 1. 01 .5 2.0 2.5 3.0 3.5 4.0 4.5 maximum wa ve 260c second prehea t firs t prehea t maximum temper at ure 260?c, time within 5?c of peak 20 seconds maximum prehea t zone r amp ra te <3?c/s 60 - 1 50 sec > 21 7?c prehea t zone prehea t d well r amp ra te <2c/s maximum temper a ture 230c temper a ture c time (minutes) 250 20 0 15 0 10 0 50 0 0 0.5 1 .0 1 .5 2.0 2.5 3.0 3.5 4.0 40-80 seconds abo ve 1 83c temper a ture c temper a ture c time (minutes) 30 0 250 20 0 15 0 10 0 50 0 0 1 .0 2.0 3.0 4.0 5.0 6.0 7. 0 figure 14 . refl ow solder pr ofile figure 15 .w a ve solder pr ofile figure 16 . lead-free re-flow solder pr ofile time (minutes) 30 0 250 20 0 15 0 10 0 50 0 0.0 0.5 1. 01 .5 2.0 2.5 3.0 3.5 4.0 4.5 maximum wa ve 260c second prehea t firs t prehea t maximum temper at ure 260?c, time within 5?c of peak 20 seconds maximum prehea t zone r amp ra te <3?c/s 60 - 1 50 sec > 21 7?c prehea t zone prehea t d well r amp ra te <2c/s maximum temper a ture 230c temper a ture c time (minutes) 250 20 0 15 0 10 0 50 0 0 0.5 1 .0 1 .5 2.0 2.5 3.0 3.5 4.0 40-80 seconds abo ve 1 83c temper a ture c temper a ture c time (minutes) 30 0 250 20 0 15 0 10 0 50 0 0 1 .0 2.0 3.0 4.0 5.0 6.0 7. 0 figure 14 . refl ow solder pr ofile figure 15 .w a ve solder pr ofile figure 16 . lead-free re-flow solder pr ofile time (minutes) 30 0 250 20 0 15 0 10 0 50 0 0.0 0.5 1. 01 .5 2.0 2.5 3.0 3.5 4.0 4.5 maximum wa ve 260c second prehea t firs t prehea t maximum temper at ure 260?c, time within 5?c of peak 20 seconds maximum prehea t zone r amp ra te <3?c/s 60 - 1 50 sec > 21 7?c prehea t zone prehea t d well r amp ra te <2c/s maximum temper a ture 230c temper a ture c time (minutes) 250 20 0 15 0 10 0 50 0 0 0.5 1 .0 1 .5 2.0 2.5 3.0 3.5 4.0 40-80 seconds abo ve 1 83c temper a ture c temper a ture c time (minutes) 30 0 250 20 0 15 0 10 0 50 0 0 1 .0 2.0 3.0 4.0 5.0 6.0 7. 0 refow solder profle wave solder profle leadCfree re-fow solder profle figure 14 figure 15 figure 16 ? 2013 littelfuse, inc. varistor products mla varistor series surface mount multilayer varistors (mlvs) > mla series specifcations are subject to change without notice. please refer to www.littelfuse.com/series/ml.html or mla.html for current information.
