This product series has a surge capability of 600 Watts PPP per line for an 10/1000s waveform and ESD protection > 40kV. BIDIRECTIONAL DIFFERENTIAL-MODE CONFIGURATION(Figure 1) Ideal for use multimode transceiver I/O lines, telecommunications and wireless circuits, the SMLCxxC-2 Series provides up to two (2) line pairs of protection in a differential-mode T1/E1 application as depicted in Figure 1. Circuit connectivity is as follows: Line 1 is connected to Pins 1, Line 2 is connected to Pins 3, Line 3 is connected to Pins 5, Line 4 is connected to Pins 7, 2, 4, 6, 8, 15 & 16. 13 & 14. 11, & 12. 9 & 10. Figure 1. Differential-Mode Protection For T1/E1 Applications CIRCUIT BOARD LAYOUT RECOMMENDATIONS Circuit board layout is critical for Electromagnetic Compatibility (EMC) protection. The following guidelines are recommended: The protection device should be placed near the input terminals or connectors, the device will divert the transient current immediately before it can be coupled into the nearby traces. The path length between the TVS device and the protected line should be minimized. All conductive loops including power and ground loops should be minimized. The transient current return path to ground should be kept as short as possible to reduce parasitic inductance. Ground planes should be used whenever possible. For multilayer PCBs, use ground vias. 1 2 3 4 16 15 14 13 12 11 10 9 5 6 7 8 05105.R4 3/05 4 www.protekdevices.com SMLC6.5C-2 thru SMLC12C-2 PACKAGE OUTLINE & DIMENSIONS PACKAGE OUTLINE -A- SO-16 16 9 -B- P 1 8 0.010" (0.25 MM) M BM 8 PL PACKAGE DIMENSIONS DIM MILLIMETERS MIN MAX 9.80 3.80 1.35 0.35 0.40 1.27 BSC 0.19 0.10 5.80 0.25 INCHES MIN MAX G C 0 - 7 -TK 16 PL 0.010" (0.25 MM) M TBS M R X 45 D AS F J A B C D F G J K P R NOTES 0.393 10.00 0.386 4.00 0.150 0.157 0.068 1.75 0.054 0.49 0.014 0.019 1.25 0.016 0.049 1.27 BSC 0.05 BSC 0.05 BSC 0.25 0.008 0.009 0.009 0.25 0.004 6.20 0.229 0.244 0.50 0.010 0.019 MOUNTING PAD 0.050" TYP 0.030" 0.005" 1. - T - = Seating Plane and Datum Surface. 2.
