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.

*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.
