PROTECTION PRODUCTS
Typical Applications
SR2.8
10/100 Ethernet ESD Protection
10/100 Ethernet ICs are vulnerable to damage from electrostatic discharge (ESD). The fatal discharge may
originate from a charged cable (cable discharge event or CDE) or the body of a user. Charges can exceed
several thousand volts under the right conditions. If the circuit is left unprotected, the voltage will be capaci-
tively coupled thru the transformer, potentially damaging or latching-up the Ethernet Phy chip. The figure above
illustrates how to use the SR2.8 to protect one 10/100 Ethernet line pair. The devices are connected differen-
tially between transmit and receive line pairs. When the voltage on the data lines exceeds the TVS punch-
through (plus one diode drop), the internal rectifiers are forward biased conducting the transient current away
from the protected chip. The design takes advantage of the isolation provided by the line transformer to
suppress common mode surges.
