Description

The PEP01-5841 has been designed to protect

power over ethernet PSE equipment against line

overvoltages. It embeds 4 decoupling capacititors

to stabilize power supplies.

It is compatible with IEEE 802.3af-2003 and

IEEE 802.3at-2008 requirements and it allows

PoE based systems to be protected against both

electrical overstress (EOS) and electrostatic

discharges (ESD) according to IEC61000-4-5 and

IEC61000-4-2.

The low clamping voltage (100 V) makes it

compatible with PMOS and PSE controller

technologies. Developed in Planar technology, it

provides high reliability level.

Packaged in SO-8, this minimizes PCB

consumption (footprint in accordance with the

IPC 7531 standard).
