Power Over Ethernet (PoE)
Objective
Power over Ethernet (PoE) interfaces
combine two Vp-p differential signals and
nominal 48 VDC power. This solution
provides protection for both the data and
power signals.
Solution
2 TVS Diode Arrays: CDNBS08-PLC03-3.3
2 Rectifier Diode Arrays: CDNBS04-B08200
1 Discrete TVS Diode: SMBJ58A
1 Multifuse® PTC: MF-SMDF050
Compliance
IEEE802.3af and IEEE802.11af
IEC 61000-4-2 Level 4 (8 kV / 15 kV)
Alternate Recommendations
Other PortNote™ Solutions:
• Ethernet - ESD Protection
• Ethernet - Power Contact and Surge Protection
Contact Bourns for PoE+ or Gbit PoE ports.
Benefit
This solution provides protection for PoE without
impairing the Ethernet signal.
