APPLICATION NOTES
The PSMS Series are TVS arrays designed to protect I/O or data lines from the damaging effects of ESD (> 25kV) or EFT. This product series
provides both unidiretional and bidirectional protection, with a surge capability of 350 Watts PPP per line for an 8/20µs waveform.
UNIDIRECTIONAL COMMON MODE CONFIGURATION (Figure 1)
The PSMS Series provides up to four (4) lines of protection in a common mode configuration as depicted in Figure 1.
Circuit connectivity is as follows:
✔
✔
✔
✔
✔
Line 1 is connected to Pin 1.
Line 2 is connected to Pin 3.
Line 3 is connected to Pin 4.
Line 4 is connected to Pin 6.
Pin 5 is connected to ground.

CIRCUIT BOARD LAYOUT RECOMMENDATIONS
Circuit board layout is critical for Electromagnetic Compat-
ibility (EMC) protection. The following guidelines are
recommended:
LINE 1
LINE 2
✔
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.
3

6
✔
✔
✔
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 induc-
tance.
LINE 3
LINE 4

Common-Mode I/O Port Protection
✔
Ground planes should be used whenever possible.
For multilayer PCBs, use ground vias.
