APPLICATION NOTE
The PSLC Series are TVS arrays designed to protect I/O or data lines from the damaging effects of ESD and EFT. This product series provides both
unidirectional and bidirectional protection, with a surge capability of 350 Watts PPP per line for an 8/20µs waveform and ESD protection > 40kV.
UNIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1)
The two PSLC Series devices provide protection in a common-mode
configuration as depicted in Figure 1.

Circuit connectivity is as follows:
✔ TVS Device 1: Line 1(D+) is connected to Pins 2 & 3.
✔ TVS Device 2: Line 2(D-) is connected to Pins 2 & 3.
✔ Both TVS Devices: Pins 1 & 4 connected to ground.

BIDIRECTIONAL DIFFERENTIAL-MODE CONFIGURATION (Figure 2)
The PSLCxxC Series provides protection in a differential-mode configuration
as depicted in Figure 2.
Circuit connectivity is as follows:
✔ Line 1(RX) is connected to Pins 1 & 4.
✔ Line 2(TX) is connected to Pins 2 & 3.
✔
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.
