Description
The PEP01-5841 has been designed to protect
power over Ethernet PSE equipment against line
overvoltages. It embeds 4 decoupling capacitors
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).
