• Line 2 connected to Pin 2 of Device 1 and Pin 1 of Device 2.
• 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.
