APPLICATION NOTE

The SMDAxxLC & SMDAxxLCC Series are TVS arrays designed to protect I/O or data lines from the damaging effects of ESD, EFT and other types of surges. This product series provides both unidirectional and bidirectional protection, with a surge capability of 500 Watts PPP per line for an 8/20µs waveform and ESD protection > 40kV.

UNIDIRECTIONAL COMMON-MODE CONFIGURATION(Figure 1)

The SMDAxxLC Series provides up to four (4) lines of protection in a common-mode configuration as depicted in Figure 1. Circuit connectivity is as follows:

✔ Line 1 is connected to Pin 5. ✔ Line 2 is connected to Pin 6. ✔ Line 3 is connected to Pin 7. ✔ Line 4 is connected to Pin 8. ✔ Pins 1-4 are connected to ground.

BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 2)

Ideal for Ethernet applications, SMDAxxLCC Series provides up to four (4) lines of protection in a common-mode configuration as depicted in Figure 2.

Circuit connectivity is as follows:

✔ TPIN is connected to Pin 5. ✔ TPIP is connected to Pin 6. ✔ TPON is connected to Pin 1. ✔ TPOP is connected to Pin 2.

✔ Pins 3, 4, 7 & 8 are connected to ground.

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.
