Ethernet Quad Port Power over Ethernet (PoE) PSE Unit Protection Solution Products Objective Alternate Recommendations 1 TVS Diode Array: CDNBS08-T58CC 4 Quad Transformers: PT61020EL Other PortNote® Solutions: • Ethernet - ESD Protection • Ethernet - Power Contact and Surge Protection • Ethernet - 10/100 Base-T Power over Ethernet (PoE) PSE Unit Protection • Ethernet - 10/100 Base-T Power over Ethernet (PoE) PD Unit Protection Contact Bourns for PoE+ or Gbit PoE port solutions. Compliance* Benefit IEC 61000-4-2 Level 4 (30 kV) IEC 61000-4-5 Level 2 (1KV) This solution provides ESD and Surge protection, low clamping voltage compatible with PMOS and PSE controller voltage as well as low input leakage current within a minimal PCB area. Power over Ethernet (PoE) interfaces combineVPP differential signals and nominal 48 VDC power. This solution provides the protection for the quad port power section in Power over Ethernet (PoE and PoE+) according to IEEE 802.3. CDNBS08-T58CC Solution PT61020EL + PSE Controller RJ-45 -48 V PT61020EL RJ-45 PT61020EL CDNBS08-T58CC Design Kit RJ-45 *The Bourns© model CDNBS08-T58CC Diode Array helps ensure the circuit protection for Power over Ethernet (PoE) applications’ compliance to IEC 61000-4-2 Level 4 (30 kV) and IEC 61000-4-5 Level 2 (1 kV) as it clamps the overvoltage transients on the lines protected and is rated to IEC 61000-4-2 Level 4 (30 kV) and IEC 61000-4-5 Level 2 (1 kV). The schematic shown here illustrates the application and does not constitute the complete circuit design. Customers should verify actual device performance in their specific applications.
