100Base-T Protection
Capacitance across the pair of wires = (D1 || D2) + P0640EA/SA + (D3 || D4)
The MUR 1100E pair of diodes capacitance is approximately (10 pF || 10 pF) 20 pF. Then,
adding the capacitive effect of the P0640EA/SA (typically 50pF), the total capacitance
across the pair of wires is approximately 8 pF. This will provide a GR 1089 intra-building
compliant design. (Figure 3.45)
Note: MURS160T3 is a SMT equivalent of the MUR 1100E.

The P0642SA is a very low capacitance device that requires no compensating diodes.
