## LCDA12C-1 and LCDA15C-1 ## **PROTECTION PRODUCTS** ## Description The LCDAxxC-1 is a low capacitance transient voltage suppressor (TVS) diode array. It is designed to protect sensitive CMOS ICs from the damaging effects of ESD and lightning. Each device will protect one line in common (line-to-ground) mode or one line pair in metallic (Line-to-line) mode. They are low capacitance (< 15pF) making them suitable for use on high-speed telecom and datacom interfaces without signal degradation. The configuration of the LCDAxxC-1 has been optimized for easy layout on high density boards. The small SOT-143 package minimizes required board space. These devices will handle up to 20 Amps for an 8/20µs lightning impulse. The low inductance construction minimizes voltage overshoot during high current surges. The LCDAxxC-1 may be used to protect ADSL interfaces, multi-protocol serial transceivers, portable electronics, and wireless systems. ## Low Capacitance TVS Diode Array PRELIMINARY ## Features - Transient protection to high-speed data lines IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) IEC 61000-4-5 (Lightning) 0.5kV, 12A (8/20µs) -

The device is designed to protect one line in common mode (Line-to-Ground) or one line pair in metallic (Line-to-Line) mode. For metallic mode protection, the input of line 1 is connected at pin 1 and the output is connected at pin 4. Likewise, the input of line 2 is connected at pin 2 and the output is connected at pin 3. For common mode protection, ground either pins 1 and 4 or pins 2 and 3. The ground connection should be made directly to the ground plane for best results. ## ADSL Protection A typical ADSL protection circuit is shown in Figure 3. The LCDA12C-1 (or LCDA15C-1 for 15 volt drivers) is connected from each line to ground on the IC side of the line. They provide lightning and ESD protection for the sensitive line driver IC. ## Matte Tin Lead Finish Matte tin has become the industry standard lead-free replacement for SnPb lead finishes. A matte tin finish is composed of 100% tin solder with large grains. Since the solder volume on the leads is small compared to the solder paste volume that is placed on the land pattern of the PCB, the reflow profile will be **==> picture [134 x 83] intentionally omitted <==** **----- Start of picture text -----**<br> Line<br>LineIn 1 4 Out<br>Line 2 3 Line<br>In Out<br>**----- End of picture text -----**<br> Figure 1 - Connection for Differential Protection (Line-to-Line) **==> picture [133 x 102] intentionally omitted <==** **----- Start of picture text -----**<br> Line<br>LineIn 1 4 Out<br>2 3<br>**----- End of picture text -----**<br> ## Figure 2 - Connection for Common Mode Protection (Line-to-Ground) determined by the requirements of the solder paste.
