APPLICATION NOTE
The SMLCxxC-2 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 600 Watts PPP per line for an 10/1000µs waveform and ESD protection > 40kV.
BIDIRECTIONAL DIFFERENTIAL-MODE CONFIGURATION(Figure 1)
Ideal for use multimode transceiver I/O lines, telecommunications and wireless circuits, the SMLCxxC-2 Series provides up to two (2) line pairs of
protection in a differential-mode T1/E1 application as depicted in Figure 1.
Circuit connectivity is as follows:
✔ Line 1 is connected to Pins 1, 2, 15 & 16.
✔ Line 2 is connected to Pins 3, 4, 13 & 14.
✔ Line 3 is connected to Pins 5, 6, 11, & 12.
✔ Line 4 is connected to Pins 7, 8, 9 & 10.
CIRCUIT BOARD LAYOUT RECOMMENDATIONS
Circuit board layout is critical for Electromagnetic
Compatibility (EMC) protection. The following
guidelines are recommended:
Figure 1. Differential-Mode Protection For T1/E1 Applications
✔ 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.
