FIgURe 1 - UNIDIRecTIONaL cOMMON-MODe pROTecTION
A SMDAxxCM can protect up to 7 I/O lines. Each, a bidirecꢀonal device, can be used on the data lines with signals that are ac in nature. i.e. their
amplitude being posiꢀve and negaꢀve with respect to ground.
The standoff voltage (VWM) and breakdown voltage (BVR) specificaꢀons apply to the Differenꢀal voltage applied across any two pins. Taking the
SMDA24CM as an example for further discussion, it being a 24V rated device it can handle ±12V between any two lines. The SMDA24CM is con-
nected as follows:
• Pins 1,3,4,5,6,7,8 are connected to the lines that need protecꢀon.
• Pin 2 is connected to ground. (Any one pin from Pins 2,3,6 and 7 can be chosen to be the ground pin. They provide shorter path to the current
within the chip.) During PCB design ensure that the Ground connecꢀon made to Pin 2 is directly to the ground plane to avoid needless para-
siꢀc inductance that can be introduced by longer PCB traces.

Circuit board layout is criꢀcal for electromagneꢀc compaꢀbility protecꢀon. The following guidelines are recommended:
• The protecꢀon 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 conducꢀve 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 parasiꢀc inductance.
• Ground planes should be used whenever possible. For mulꢀlayer PCBs, use ground vias.
