V18MLN41206

Multiline Transient Voltage Surge Suppressor RoHS MLN SurgeArray™ Suppressor 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. The inherent capacitance of the SurgeArray Suppressor permits it to function as a filter/suppressor, thereby replacing separate zener/ capacitor combinations. 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. The MLN can also be provided in a Dual version. Contact Littelfuse for information.

Typical profiles are shown in Figures 14 & 15 The recommended solder for the MLN SurgeArray 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 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 solderís peak temperature is essential to minimize thermal shock. TEMPERATURE ( oC)oC) TEMPERATURE ( FIGURE 14.

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 50˚C before cleaning. Lead-Free (Pb-free) Soldering Recommendations Littelfuse offers the 0805 array as the preferred solution for lead-free soldering conditions. The preferred solder is 96.5/3.0/0.5 (SnAgCu) with an RMA flux, but there is a wide selection of pastes & fluxes available with which the nickel barrier parts should be compatible. The reflow profile must be constrained by maximums shown in Figure16. For Pb-free Wave soldering, Figure 15 still applies. Note: the Pb-free paste, flux & profile were used for evaluation purposes by Littelfuse, based upon industry standards & 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. 1.5 TIME (MINUTES) 3.0 2.0 2.5 TIME (MINUTES) FIGURE 15.
