Two PSOTxxLC devices used in parallel. Circuit connecvity is as follows:
• I/O Line connected to Device 1, Pin 1.
• I/O Line connected to Device 2, Pin 2.
• Device 1, Pin 2 connected to ground.
• Device 2, Pin 1 connected to ground.
• Device 1 and 2, Pin 3 not connected.
Circuit board layout is crical for electromagnec compability protecon. The following guidelines are recommended:
• The protecon 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 conducve 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 parasic inductance.
• Ground planes should be used whenever possible. For mullayer PCBs, use dedicated ground planes
