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 P_PPper line for an 8/20µs waveshape and offers ESD protection >

40kv.

BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1)

Ideal for use multimode transceiver I/O lines, the PLCDAxxC-6 Series provides up to six (6) lines of protection in a common-mode configuration as

Figure 1: Typical Transceiver Protection Circuit

LINE 6

depicted in Figure 1.

LINE 5

LINE 4

LINE 3

Circuit connectivity is as follows:

✔

Line 1 is connected to Pin 1.

Line 2 is connected to Pin 2.

Line 3 is connected to Pin 3.

Line 4 is connected to Pin 8.

Line 5 is connected to Pin 7.

Line 6 is connected to Pin 6.

Pins 4 and 5 are connected to Ground.

LINE 2

LINE 1

BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 2)

The PLCDAxxC-6 Series also provides video line applications six (6) lines of protection in a common-mode configuration as depicted in Figure 2.

Circuit connectivity is as follows:

✔

Line 1 (Red) is connected to Pin 1.

Line 2 (Green) is connected to Pin 2.

Line 3 (Blue) is connected to Pin 3.

Line 4 (VSYNC) is connected to Pin 6.

Line 5 (HSYNC) is connected to Pin 7.

✔

Pins 4 and 5 are connected to Ground.

CIRCUIT BOARD LAYOUT RECOMMENDATIONS

LINE 1 (RED)

Circuit board layout is critical for Electromagnetic

Compatibility (EMC) protection. The following

guidelines are recommended:

LINE 2 (GREEN)

LINE 3 (BLUE)

✔

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.

DB-15

CONNECTOR

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.

LINE 4 (VSYNC)

LINE 4 (HSYNC)

✔

Ground planes should be used whenever

possible. For multilayer PCBs, use ground vias.
