Circuit connectivity is as follows: • Pin 1 on each device connected to data lines. • Pin 2 on each device connected to ground. • Pin 3 not connected. circuit board recommendations Circuit board layout is critical for electromagnetic compatibility 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. 05100.R8 9/10 Page 6 www.protekdevices.com 05100 PLC497 Only One Name Means ProTek’Tion™ sot-23 package information outline dimensions dim millimeters A L inches min max min max A 2.80 3.04 0.110 0.120 B 1.20 1.40 0.047 0.055 C 0.89 1.11 0.035 0.044 D 0.37 0.50 0.015 0.020 G 1.78 2.04 0.070 0.081 H 0.013 0.100 0.001 0.004 J 0.085 0.177 0.003 0.007 K 0.45 0.60 0.018 0.024 L 0.89 1.02 0.035 0.040 S 2.10 2.50 0.083 0.098 V 0.45 0.60 0.018 0.024 3 B 1 0°-10° S 2 K V J G C D H NOTES 1. 2. 3. 4.
