| Features and Description |
 |
2 Bidirectional Transil functions |
|
Breakdown voltage: VBR = 14.2 V and 25 V minimum |
|
Low leakage current: < 1 µA |
|
Low diode capacitance: 14 and 8 pF at 3 V |
|
Very small PCB area < 2.6 mm2 |
|
The ESDALCxx-2BP5 is a monolithic
array designed to protect up to 2 lines against
ESD transients.
The ESDALCxx-2PB5 has
been developed according to the following requirements:
|
•
|
Line driver power supply voltages |
•
|
Compliance with telecommunication standards like ITU-T K20/21 & GR1089
Core which are the most stressfull when using protection on
the primary winding |
•
|
Compatibility with high DSL debit rate for the capacitance
to avoid BER or oscillation problem |
|
| Choice of either a 14.2V or a 25V Transil gives
the possibility to use both topologies: |
 |
 |
| Topo. 1: ESDALC25-2BP5 protection on
Tx & Rx |
Topo. 2: ESDALC14V2-2BP5 on secondary
winding |
| In this case, one Transil is used to protect Tx while the
second one is used to protect Rx. |
In this case, each secondary winding of the transformer is
protected. For both topologies, the SOT-665 must
be implemented as close as possible to the transformer to avoid
disturbances on the board. |
