PLC496
APPLICATION NOTE
The PLC496 is an ultra low capacitance, bidirectional array that is designed to protect I/O or high speed data lines from the damaging effects of ESD
or EFT. This product has a surge capability of 500 Watts PPP per line for an 8/20µs waveshape and offers ESD protection > 40kV.
DIFFERENTIAL-MODE CONFIGURATION (Figure 1)
The PLC496 is designed to protect one bidirectional line where the normal signal
voltage is both positive and negative. Figure 1 shows a typical differential-mode
line to line) I/O port protection circuit application.
Figure 1. Typical Differential Mode I/O Port Protection
Circuit connectivity is as follows:
✔ Pins 1, 4 5 and 8 are connected to the data lines
✔ Pins 2, 3, 7 and 6 are not connected.

The PLC496 can provide protection for sensor circuit applications. Figure 2, is a
typical common-mode (line to ground) sensor circuit application.
Circuit connectivity is as follows:
✔ Pins 1 and 8 connected to the dataline
✔ Pins 4 and 5 connected to ground
✔ Pins 2, 3, 6, and 7 are not connected
CIRCUIT BOARD LAYOUT RECOMMENDATIONS
Circuit board layout is critical for Electromagnetic
Compatibility (EMC) protection. The following guidelines
are recommended:
LINE 2 IN
LINE 2
OUT
✔
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.
Figure 2. Typical Common Mode Sensor Protection Circuit
✔
✔
✔
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.
SENSOR
CIRCUITRY
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.
