55) ' 6 6 the psmf series are tvs arrays designed to protect i/o or data lines from the damaging effects of esd (> 25kv) or eft. this pr oduct provides unidirectional protection, with a surge capability of 200 watts p pp per line for an 8/20s waveform. unidirectional common mode configuration (figure 1) the psmf series provides up to four (4) lines of protection in a common mode configuration as depicted in figure 1. circuit connectivity is as follows: i/o 1 is connected to pin 1. i/o 2 is connected to pin 3. i/o 3 is connected to pin 4. i/o 4 is connected to pin 5. pin 2 is connected to ground. circuit bo ard la y out recommend a tions 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. figure 1 - unidirectional configuration common-mode i/o port protection 3 1 5 2 4 i/o 4 i/o 3 i/o 2 i/o 1 i/o integrated circuit
