APPLICATION NOTE
The PLCDAxxC-6 Series are low capacitance, bidirectional TVS arrays that are designed to protect I/O or high speed data lines from the damaging
effects of ESD or EFT. This product series has a surge capability of 500 Watts PPP per line for an 8/20µs waveshape and offers ESD protection >
40kv.
BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1)

CIRCUIT BOARD LAYOUT RECOMMENDATIONS
LINE 1 (RED)
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.
