FIGURE 3 - BIDIRECTIONAL DIFFERENTIAL mODE PROTECTION 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. 05135.R10 9/10 Page 6 www.protekdevices.com 05135 Only One Name Means ProTek’Tion™ SLVU2.8 SOT-23 PACkAGE INFORmATION OUTLINE DImENSIONS DIm A B C D G H J K L S V 1. 2. 3. 4.
