TION NOTE
The PSMS Series are TVS arrays designed to protect I/O or data lines from the damaging effects of ESD or EFT. This product series provides both
unidirectional and bidirectional protection, with a surge capability of 350 Watts P
PP
per line for an 8/20µs waveform and ESD protection > 25 kilovolts.
UNIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1)
The PSMS Series provides up to four (4) lines of protection in a common-mode configura-
tion 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.
✔
Pin 2 is not connected.
BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 2)
The PSMSxxC Series provides up to four (4) lines of protection in a common-mode
configuration as depicted in Figure 2.
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 5.
✔
Pin 6 is connected to ground.
✔
Pin 2 is not connected.
CIRCUIT BOARD LAYOUT RECOMMENDATIONS
Circuit board layout is critical for Electromagnetic
Compatibility (EMC) protection. The following
guidelines are recommended:

LINE 4
✔
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.
