Note 1: Devices are designed to be used in parallel (See Circuit Diagram). For other applications, contact the factory. Do not apply surge in the
“forward” direction of the TVS.
Note 1: Do not surge from pins 8 to 1, 2 to 7, 6 to 3 and 4 to 5. PIV typically greater than 100V for each rectifier die. Electrical characteristics apply
to pins 1 to 8, 7 to 2, 3 to 6 and 5 to 4.

APPLICATION NOTE
The PLCDA 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)
Ideal for use in USB applications, the PLCDA Series provides up to two (2) lines of protection in a common-mode configuration as depicted in Figure
1.
Circuit connectivity is as follows:
✔ Pins 1 & 2 and 3 & 4 are connected to Ground
✔ Pins 5 and 6 are connected to I/O Line D+
✔ Pins 7 and 8 are connected to I/O Line D-
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.
