APPLICATION NOTE

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.

The SMS Series are TVS arrays designed to protect I/O or data lines from the damaging effects of ESD or 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 > 25 kilovolts.

UNIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1)

The SMS Series provides up to four (4) lines of protection in a common-mode configura-

tion as depicted in Figure 1.

Circuit connectivity is as follows:

✔Line 1 is connected to Pin 1.

✔Line 2 is connected to Pin 3.

✔Line 3 is connected to Pin 4.

✔Line 4 is connected to Pin 6.

✔Pin 5 is connected to ground.

✔Pin 2 is not connected.

BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 2)

The SMSxxC Series provides up to four (4) lines of protection in a common-mode

configuration as depicted in Figure 2.

Circuit connectivity is as follows:

✔Line 1 is connected to Pin 1.

✔Line 2 is connected to Pin 3.

✔Line 3 is connected to Pin 4.

✔Line 4 is connected to Pin 5.

✔Pin 6 is connected to ground.

✔Pin 2 is not connected.
