Power over Ethernet (PoE) Applications: Trends and the Need for Robust Protection

The Growing Role of PoE

Power over Ethernet (PoE) technology is increasingly becoming the backbone for powering and connecting network devices, from IP cameras and wireless access points to smart lighting systems. The latest IEEE 802.3bt standard supports up to 90W per port, and industrial implementations often operate up to 58V voltage. With this higher voltage and greater power capacity comes a growing need for robust protection solutions to ensure reliability, safety, and compliance with industry standards.

Many advanced PoE systems support both DC input and PoE input, enabling flexible power sourcing. These inputs are often connected via an OR-ing power architecture.

To ensure seamless and reliable power path selection without excessive power loss – 

Ideal Diodes M74700 rated for 58V operation are used. The device provide:

      • Low forward voltage drop to improve efficiency.
      • Fast switchover for uninterrupted operation.
      • Reverse current blocking 
      • Revers Polarity Protection with +/-100Vdc

Surge and ESD Protection for PoE and Ethernet

  • POE 58V Power Line Surge Protection 
      • 5.0SMDJ58A/CA, 5000W SMC Package TVS
      • Ultra Low Clamp TVS 5.0SMDJ58CA-n
  • Ethernet high speed data lines TX/RX
      • CSLS05U4G (Lin to GND)
      • SRV05-4D (Line to Line)
      • SP03-6BTG (Line to Line)
