The PSMF Series are TVS arrays designed to protect I/O or data lines from the damaging effects of ESD (> 25kv) or EFT. This product provides
unidirectional protection, with a surge capability of 200 Watts P
PP
per line for an 8/20μs 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 BOARD LAYOUT RECOMMENDATIONS
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.
