APPLICATION NOTE
The PSMF Series are TVS arrays designed to protect I/O or data lines from the damaging effects of ESD or EFT. This product provides unidirectional
protection, with a surge capability of 200 Watts PPP per line for an 8/20µs waveform and ESD protection > 25 kilovolts.
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 BOARD LAYOUT RECOMMENDATIONS
5
1
4
3
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.
2
✔
✔
✔
The path length between the TVS device and
the protected line should be minimized.
I/O 2
I/O 1
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.
