This product series provides both unidirectional and bidirectional protection, with a surge capability of 500 Watts PPP per line for an 8/20s waveform and ESD protection > 40kV. UNIDIRECTIONAL COMMON-MODE CONFIGURATION(Figure 1) The SMDAxxLC Series provides up to four (4) lines of protection in a common-mode configuration as depicted in Figure 1. Circuit connectivity is as follows: Line 1 is Line 2 is Line 3 is Line 4 is Pins 1-4 connected to Pin 5. connected to Pin 6. connected to Pin 7. connected to Pin 8. are connected to ground. Figure 1. Unidirectional Common-Mode Protection LINE 1 LINE 2 LINE 3 LINE 4 BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 2) Ideal for Ethernet applications, SMDAxxLCC Series provides up to four (4) lines of protection in a common-mode configuration as depicted in Figure 2. Circuit connectivity is as follows: TPIN is connected to Pin 5. TPIP is connected to Pin 6. TPON is connected to Pin 1. TPOP is connected to Pin 2. Pins 3, 4, 7 & 8 are connected to ground. 1 2 3 GND PLANE 8 7 6 5 4 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.
